I've been using excel for a while, then I got a new computer, installed
excel, then tried to do some formatting. Some formats are gone. I see
duplicates.

What I am trying to do is format negative numbers to be in brackets. I have
found a custom format that does this, but the format style I want used to be
under number. Now I just see the first two format types under number repeated.

Is there a way that I can fix this? Can I fix it without reinstalling excel,
or would that be the best fix?

Any help would be great.
