Can't see reference type when editing output style

I just updated to 21.1 on Mac, and hoped that this error would be fixed, but I didn’t see a change. I cannot see the reference type for each template when I’m editing the output style. This applies on the citations or bibliography page for a reference style:

It seems like the labels are there in the output style window, but they are just hidden by the layout. For example, on the one I have selected in blue in the image, there is a row of underlined text above but it is cut off.

I’m experiencing this issue, too, including with the most up-to-date endnote version. It makes Endnote unusable and I’ve started switching over to Zotero.
