My detailer put too much compound?

I took my car to someone to get it detailed, and I was supposed to get a 1-step paint correction/polish on the whole car and then ceramic coat. After the job was done, I notice around the taillights and then also the the rubber seals around my windows seem to have white compound on them. The compound does not come off with water or even when I washed the car.

It makes a lot more sense for this to be the polish compound, so does anyone have any ideas to what I'd need to do to get these marks off?
