Crown too low - It was too high and went back in and filed down. Advise?

I have a newly placed zirconia crown on tooth number 15 there is also a zirconia crown 18. It was too high and went back in and filed down. Now I’m worried it was too much. It’s not contacting as much as the neighboring tooth. Also there was a small irregular “step” at the margin line that came off while eating. I’m going back but I’m concerned.
