Mysterious duplicate of picture/ text on another layer

Hey guys, i have s strange problem, when i try to resize a picture or to change a text, photoshop creates a copy of the text / picture on another existing random layer, when i disable and renable the other the layer the copy  of the text/ picture disappears.

It's impossible to work with text, 'cause everytime i try to edit it, theres a copy created behind it..

You know what i'mean? Is this a new bug?
Please somebody help me, don't know that to do! 

Thanks guys! 🙂
