Strange things happen
When I tied to remove the modules in reverse order, as you recommanded, I could easily remove all of them. After that with the Allbuton, all modul appeared and I could make them either disappear all together or one by one from any direction, means from the bottom to the top or in reverse order.
By now the Edit modules funktion is just working fine, just don’t know why. :relaxed:
So have a big Thank you for your help
