Light building not working

Hi, I´m dealing with a problem when I build the lightmap. Workflow is fine when I start a new level, the issue appears when I try to build the lights, it finishes correctly but light never changes. I looked for some answers and I found one that worked for a moment, but when I start changing lights values it breaks again.

The solution that worked for a moment was: Going to (C:)/Users/PCname/AppData/UnrealEngine and delete everything the folder contains.

I tried that and when I opened my level it seemed perfect, then I changed light values and broked again.
Any help please? :frowning:
