My game keeps saying I left mid match when I didn’t causing me to get penalty’s

Ghost_21

My game is saying I left the game and giving me a penalty when I didn’t

At the end of my match when I was loading back into the lobby I closed the game (I had finished my match and everything) 

I played as a survivor (to be specific I was being feng)

It gave me a 70 hour penalty this also isn’t the first time this has happened 

The characters I played was Feng Min

The perks I had were Technician, Alert, Lithe and Decisive Strike

I don’t remember the map

The console I was playing on was PS4

it also causes my Survivor rank to go down which is quite annoying having to go and level back up just for this to happen again.
