PS4 won't update a game, please help

I'm trying to update to the latest version of overwatch as every time I start the game it tells me to close it and install the update. However when I 'check for update' my PS4 is telling me that my game is updated to it's latest version.

I've tried multiple times to restart my PS4 but that has not worked to fix the problem.

Does anyone have any idea how to help? I'm definitely not an expert on this so any advice would be welcome.
