Text frame Auto-size problems

Hello!

I create a lot of flyers with InDesig CS6. I need to put the informations onto the product photo. To speed up my work I apply on this text frames the feature automatic resizing, but I have some problems with that.

• If I duplicate the text frames, sometimes they lose the resizing settings.
• When I use lot of tfs with these settings inside one document iD slows down extremly.
• If I try to copy one of these text frames into Photoshop, InDesign chrases.
• Randomly the resized text frame not follows the length of text but stretched out of thework area.
  

Is it simply a bug or what I doing wrong?

Thanks for any help!
