Light Bleeding on walls and floor

hey so ive been reading around and tried a bunch of stuff on here to fix this but cant get it too work, my lightmaps are snapped to the grid with about 3 to 4 padding and i have tried to up the lightmap res
the floor mesh in the image has a 2048 res lightmap and it still isnt fixing it the wall piece in the middle has a 1024 and the piece on the right has a 1024 and nothing, the wall on the left in the first image is the only one i have been able to fix by upping the lightmap res
any tips on how to get rid of this?
