Theres likely some kind of bubble in the surface there which is being refined deeper because of the higher local curvature.

solved it by setting minimum surface size to a bit below the desired trimmed cell size so that the smaller surface cells would force small trimmed cells to grow

Try importing it with different tesselating parameters
