I found this topic that describes the same issue I’m having:
I saw the thread was closed mid June, but I just ran into the issue around mid July. I hadn’t been cutting much from May until early July. When copying and pasting objects in the app, sometimes instead of pasting the object I copied, the app just moves a previously modified object to the spot where it would have pasted the copied object. It happened a few times while setting up my cut, but I eventually got everything where I wanted it. When I ran the cut file, however, some objects were re-positioned, and some were replaced with others.
This problem only happens with copy paste in the app. I’ll have time to get some pictures of the issue this weekend if needed.
