User can dissolve some activities, but not others

Hello,

I have a user who can dissolve some activities in the WBS Band where he has permission, but not others.

When I copy his user into a new user profile, it will allow him to dissolve all activities for a day, but then the next day, he can not dissolve some of the activities, again.

His user profile is a mirror of another user's profile in his area.  The other user has had no problems.

I have also tried copying the other user's profile to create his profile and the same one day period occurs where he can dissolve and the next day, he can not.
