No lights when changing shadow quality in Unreal 4.17

Hello to everyone. I just made a new copy of my project from 4.15.3 to 4.17. Everything works fine except for the point lights that behave like they are turned off whenever I am changing the quality from Lowest to anything else.

I really like the new features of 4.17 and I want to try and find a solution for this. Any ideas?
