Glitch in Reward Room #5 (Help)

Hi, I think there was glitch in one of the rewards room. I was stuck in the sofa chair when the timer counted down, and I teleported to the neon chair and it counted down a 2nd time. So I have 1 more reward than I was supposed to have. (I don't want to be penalized for the '15 minute' rule)

I have screenshots saved onto my computer, but I'm not sure how to post it.

Thanks~
