Why can't I add captions to new photos added to an existing photo.

[StudioCC]

I have an existing photo gallery that accepts additional photos, but will not
take captions/descriptions for the new photos.
I have even tried creating an new photo gallery with these same photos, but
still cannot put on captions/descriptions for these photos. How do I
"unlock" this procedure?

Since I have had no replys and have been unable to find reference to this
particular problem I am replying to my own post: I used the "detect and
repair" under help in FP and this cleared the problem.
Maybe for anyone having similar problems this should be the 1st "line of
action".
