Kemper Stage warped ?

Until last night my Kemper Stage has been used while sitting on carpet and pad. I sat it on a level hardwood surface and noticed that not all 4 feet set flush on the floor causing it to teeter-totter slightly. Does anyone else have this issue?

I was going to take the feet off as well but, my Stage had other additional issues too so, Kemper replaced it. All is well now.

Thank you Kemper team!!
