How to validate workout?

Hello,

I just started the program FB Adventure and it has been great so far. I am enjoying myself and considering how sore I am, I realise I DO have muscle :)

Something is annoying me though: I look at the videos from start to end but FB tells me I havent completed the workout and I have to force and use the "mark as completed" button. I know this is ridiculous but I feel I'm cheating...

Is there a way that th workouts get automatically validated?

Thanks for your help!
