wrong caption action and associated control

Hello,

I use the commandbars with the Actions enabled. However, if I set the caption of an action object all the associated commandbar controls still keep their original caption.

I tried to debug this, and when I display the caption of the commandbar control and the caption of the action control of this commandbar control I see different captions! With other properties of the Action object it goes right, like checked, tooltiptext, enabled, etc.
