I was able to zoom in on one of the pictures, originally it looked like you have some form of build up happening.

I can see in the picture the finish has lifted and curled at the point of bridge contact, I suspect they sprayed the paint up to and onto the bridge, so when the bridge filled, it lifted the finish all the way around it.

Not an easy repair, you need to clean / sand / stain / colour match and refinish the top, or accept it the way it is and simply glue the bridge back on.
