The Problem is that citations are supposed to be regular in normal text paragraphs and bold in picture and table captions in my case.
I already use a custom CSL (based on ISO-690), which doesn’t have any forced styles as far as I can tell.
Also something strange is still going on, when I try to work around the problem by changing the styles globally to force Word afterwards to apply the bold style in the respective paragraph:
I’m using section breaks for the caption, so that the citation is not appearing in the list of figures (this example has nen error in it, “in Anlehnung” should be in the second section of the caption, not just “an” but the principle is the same):
The first half of the caption is the actual caption, the second half is also in caption style, but isn’t listed in the list of figures.
When I derive a new style, e.g. “caption suffix” from the caption style and apply it to the second half of the caption only, Word automatically changes the style to the correct one:
When I change the styles globally, only the citation boldness of the derived styles also changes globally but the caption-styled citations will remain non-bold for captions where I keep the caption style for both parts of the caption.
When I update all citations the citations will change back to non-bold.
When I change the “caption suffix” style to non-bold globally again, Word will switch the styles and the citation will become bold altough the applied style is defined as non-bold:
Updating the citations changes the citation formatting back to non-bold:
Sooooo there still seems to be something wrong, even though the CSL might be overriding the font style when being inserted at first? Word seems just to be switching bold with non-bold when applying the style (not when making the citation bold manually by selecting it and clicking the bold button).
