Copy/Paste behaves really strange in Wix Editor

Since today I can not properly copy/paste anymore in Wix Editor. When I paste something it does not only paste my copied content but also it pastes an earlier copied object. Really strange. Anybody had this issue? Any idea how to solve it?

What are you trying to achieve:
I want to copy/paste as normal

Additional information:
Wix standard editor on Microsoft Edge
