That being the case, the problem is very like some manual formatting you've applied (or that was introduced) to the note references in your document's text that overrides the "Footnote Reference" character style. When we talk about overrides like this, it only means formatting applied to text that does not come from styles.
Explaining this another way: to decide how some piece of text in your document should look (eg: font, color, etc), Nisus Writer checks the attributes enforced by the applied styles plus manual formatting. Going from least important to most important, this list of consulted factors is:
1. The paragraph style.
2. The character style.
3. Manual formatting.
There are some other more esoteric factors (eg: if the applied paragraph style does not define a font, then the font of your document's Normal style is enforced) but they can be ignored for this discussion. Factor #3, the manually applied formatting, is what we mean by "override" because it overrides the formatting enforced by your styles.
So, to get back to your problem: your reference style sounds to be in order. Probably the only reason the text in your document hasn't been updated is because all/most of your note references have a font size override applied, which overrides the style.
Hopefully this is clear. It sounds more complicated than it really is, since in practice it's used often, say to make a single word appear bold in a paragraph which is marked in the Normal paragraph style. If you had updated the Normal style to use a different font, you wouldn't expect those single bolded words to suddenly lose their bold.
Q: 1. I don't know what an 'override' is. I can't find an actual icon called that in the manual. Do you mean the ruler icon? If so, I don't see how that applies here because "Footnote Reference" is a character Style, not a paragraph style.
If you look at the bottom-right area of any document window you should see a bunch of little icons, which are tags. There is indeed one for the ruler, but also some for fonts, colors, etc. Some of these tags are always shown (eg: the style tags), but other ones only appear if a relevant override has been applied to the current text selection.
To see if your footnote reference has some font override applied: select a footnote reference in your document's text and check if the font tag appears, whose icon is a little black underlined "a". If it shows up you can click that icon and use the menu "Remove Font" to remove all the font related overrides.
Another way to remove such overrides: use the menu
Format > Remove Attributes Except Styles, or the more specific menus like
Format > Font > Remove Font Attribute.
Q: 3. How does one go about doing "Select All" 'in' such a 'tag'? All I can think of is the sample text inside the "Footnote Reference" tag, but you don't mean that, do you?
There are a variety of ways to select all text in a particular style, one of which is to use the tag icons: select any footnote reference in your document text, click on the Character Style tag (a blue-boxed "a" icon), and use the menu "Select All". Another way is the main menu
Format > Character Style > Select All Style. Both of these will select all text in your document marked in the current character style.
Once you have all your footnote references selected at once, you can use any of the aforementioned commands to strip the font size overrides in a single action, thereby letting your footnote reference style shine through.
I hope this helps explain things. Let us know if there's still some confusion, or you have additional questions.
