At the moment (V6.4.17) it is very dangerous to CLONE a schematic back into the **same** project.
It is much safer to COPY and PASTE it.
Please read the notes in and study carefully these two projects which demonstrate some problems caused by the differences in behaviour between CLONING and COPYING and PASTING schematics both before and after reannotation.
