Materials on BSP blocks keep stretching

Im using bsp blocks on a level im designing. When ever I put the bsp blocks to form an outer corner for some reason the textures just glitches and stretches. Ive set the alignment to surface planar and that worked but whenever I moved a block it would just glitch back.
Here is a screenshot

Is there a faster way to permanently fix this?

-which engine version do you use?
-as far as I know this is a known bug -> just do the part with the alignment after you have placed everything :slight_smile:

Unreal engine 4 4.7.6

Just test it and I think it was fixed in 4.8 :slight_smile:
