Opposition healing even with healing immunity

In two Arena matches I have done today, characters with the healing immunity effect on them were able to heal. I checked the abilities of the characters in each match and there is nothing to indicate that should have been possible so it's either the classic EA a.i. cheating programming or a bug.
