FCPX Caption Editor shows black text on black background I successfully imported an iTT caption file, and the captions show up fine as white on a black background. The problem is that when I try to edit it in the caption editor, the text is black-on-black, i.e. not visible.

When I drag to select text, the selected text is white-on-purple, so the text is definitely there, just black-on-black.

Obviously this makes it difficult-to-impossible to edit my captions, which need editing. The same problem happens in the Inspector.
All the images I see on line, like this one from Larry Jordan, show white text on a black background.

Any help appreciated!
EDIT: resetting the preferences didn't solve the problem.
This seems to have been caused by a problem in the incoming iTT file. I was able to solve it by creating a new SRT caption role, selecting all the captions, moving them to the SRT role,  and then moving them back. Alternately, it looks like you can change the caption color  to something other than white, and then change it back to white.
