If I get you correctly when you remove the bottom bolt (and the little bolt with hex head on top of the filter cover) this allows the oil to drain safely back into the engine instead of out over the case when you take the cover off.

A had a similar problem before while travelling, the only thing to do was increase hole size, thread it and install a bigger bolt. When at home I wanted to helicoil it but the helicoil wall thickness was too thin - I would have had to use two so I loctited a bit of threaded bar in the hole - drilled the center of it and threaded it then drilled the first few mm again to accommodate the wide unthreaded part of the bolt. And of course the drain hole from the oil filter area to bolt hole again as the threaded bar I inserted now blocked it.

Finnicky time-consuming work making sure the holes were dead center and straight. I had to do the two upper bolts too and they come from a lot further out so have to be dead straight and centre but did the job in the end.
