Purchased p85b today and 5 keys are sticking

I purchased this keyboard today only a few hours ago and just started it up a few minutes ago. I noticed that the f,g,a, f#, g# keys are all sticking in the main octave. It wouldn't bother me so much if it were keys towards the complete ends of the keyboard but they are sticking in the main keys. It was a hassle getting this keyboard in my car and and unpacking and whatnot and I don't want to go through the inconvenience of having to wrap it back up and returning it and exchanging to find out I have the same problem. What are your recommendations? I read online this is a common problem for yamaha weighed keyboards and I love my other Yamaha and never had a problem. I would like to have this fixed
