I think this is a bug but I've managed to complete every other bit in the chase trail bit but for some reason when I accept the practice 1 mission and get 6 combo's in the arena it doesn't seem to register the fact I actually did do it?

As said , I managed to complete every other one so I know how combo's work but for some reason it doesn't register a thing

I am currently using fire main, kakashi, hinata and kabuto, so I can get a 6 combo going pretty easy in there

can I get help?
