Hello Alexandre,
i found a way to reproduce this miracle.
Please see the 7zip i has Attached and have a look at the screen for the cloning lines in Code.

I dont think this should happen?

And here the sample Project: Download here please

Hopefully it will helps you to find what is going wrong.

with friendly regards
Victoria
