No problem.
I initially thought it was related to the introduction of British English language which is a feature I enabled immediately, which supposedly does some automatic translations, but after reading the change logs I thought it could be more broadly related to the file type group changes which happened.
It's possible that the automatic translations affected the in-built file type groups (which I had renamed) and reset them? I don't know. Other file type groups which I had defined didn't lose their custom Info Tip config etc, only the in-built ones as stated.
