Leonheart fighting glitch

Why is it that leonheart misses every time I use him and it started after I died at least once I even had an extra save right before getting him to find out the cause. Please fix this if its a glitch cause his acc is 10-99% and all other characters are that level and they arent missing at all and have died lots of times. Ill give five star if this is fixed
