Hello @Luc_Zentar

I’ve just tried to reproduce it in mine and didn’t get any error. Perhaps there is a problem with your file? No problem with the old block and this file? If there is no problem with the old block, could you please share the file with us so that we can reproduce the problem ourselves?

Regards,
