again there is no bug there - from your input you're using a CV which

collective variable is defined as the SQRT of the modulus squared: so
the minus sign is not affecting anything in the definition of CV.
Clearly for the ANGLE the situation is different, and this is the
reason why there is a PBC keyword there. For DISTANCE you do not need
it, since the CV is well-behaved.
If you see something strange, then probably you should check carefully
your system and your setup: from what you've sent I can already reckon
that a cutoff of 200 on the density with BLYP is definitely
