The VMAT module does not properly detect failed segments if the r_dev is negative. Line 423, I think, is the problem because no absolute value is used:
return self.r_dev < self._tolerance * 100
If you set the tolerance at 1 % and if r_dev for a particular segment is, say, -1.1 %, the segment will still have a passing status.
