RE: Problem with polar form of complex numbers
Correct for Home,

but start in CAS

20 ∢ -45 ( 45 with +- button) OK

now grab 20 ∢ -45 from the CAS history and press Home and Enter, and you get the error. Perhaps this is the problem the OP ran into? Notice how in CAS the +- (unary) minus gets converted into the regular minus?
