bug? values exported accross files

Hello,
I’m having a problem with exported values, I think this could be considered a bug. It happens when either :

  • I have 2 files opened, and copy/paste a layer from one to another
  • I duplicate a synfig file and open both the original and the copy.
    At that point I would expect the 2 opened files to be unrelated, however, the exported values are common, modifying them in one file results in the same modification in the other. Furthermore, the value only appears in the library panel of the original file.
    All I can do is being careful not to open two “related” files at the same time…
