I am using WMM in Win 8.1, have used for years. Whenever i add captions to photos, all is fine until I go back and edit something. ie: I add a title frame for a group of pictures. The captions under the pictures that follow that frame either lose them altogether or they might shift to another picture. I then have to fix each one. I've never had that happen.  Or, if I change the runtime of the picture (7 seconds to 5 seconds) so it matches with the music play time, it will lose or shift  the caption as well.

Does anyone have this issue? Is this a bug or am I doing something wrong?
