Please ignore. Posted an answer to a different question. Still not entirely sure what the OP was trying to do, though...

Hi Phil

my understanding is: the issue was erasing into a square with outline and not realising the outline would not be erased, but redrawn round the cut

erasing into a square without an outline solved the problem

but, as always, I could be wrong...
