I have had two window leaks in my two tms. One was the sealant q outside around the window. Had to remove and reinstall window. Don't over tighten window or it will leak again. I would leave about 1/16 inch thick sealant

2nd leak was the caulk along outer edge of roof. Removed caulk front to back along edge where window is and re-caulk.
