Penthouse seal leaks at corners

I have sought the answer but have not found.
A recent road trip featuring driving rain and highway speeds resulted in water ingress at the corners of the pop top where the tent fabric is bedded down to the van roof.
I have the top up and the upholstery peeled back all the way around where screws hold a plywood strip down on top of the tent fabric, go through the butyl tape, and into the sheet metal.
At the corners, the seam in the tent fabric is turned up on top of the plywood strip. This is because the plywood would not go up over the seam.
A big wad of silicone was shot in there in hopes it would seal the corners.
It didn't.
I now have discolored plywood and mildew in the corners.
Has anyone dealt with this problem? Please advise.
I must say I was most dismayed with the workmanship I uncovered when I peeled back the upholstery.
Thanks GH
