Ninja Multicooker questions

I have the Ninja OL750 for a couple of months now and I have noticed that the main compartment has this like burn marks on them. I am not sure if this is normal or it might be indicative of a problem. On top of that I dropped in the sink the detachable pot the other day while cleaning it and there is a slight dent and it looks like it damaged some of the coating. Is this fixable or I have to acquire new one?
