This light Bleeding is there all the time, even on epic scalability and production light setings. and the farther the camera is the light passing through gets worse.
Probably is there something wrong with the material and to solve it and avoid it in the future anyone can point me in the right direction.
I suggest looking closer at the UVs. The walls have to be a certain thickness in order to avoid bleeding. I think the suggested thickness is around 10 UU (10 CM). Make sure you up the resolution of the lightmaps as well.
