I'm afraid I have no answer for that. I do know that there are issues that crop up for some users, but not others. There are some skills / gear that appear to be displaying data incorrectly at times, even though they are functioning correctly. Some issues only crop up in NG+. Some issues could not be fixed without knowingly breaking something else. I really don't know what the situation with this one is. The latest posts I can find are all summer of 2016...so that's a good sign, I guess.
In short...there's only one way to find out for sure. (Even if that particular skill is wonky, there are many ways to stick your sword through something's head!)
