I personally really want this feature to be fixed, as it shows 0 for all 4 abilities for me. I want to see how many abilities I'm using. Especially on characters like omen, I want to make sure I'm smoking enough or if I'm playing cypher, I want to make sure I'm ulting enough. Also a suggestion, set a stat for average cast per round, and also adding a stat that shows total casts throughout the entire game. If there's a mission that shows use abilities, I don't see why the same stat could be put into the performance tab.
