Hidden lightmap res. override?

Hi everyone
I have a problem with my lightmaps resolution.
When i bake lighting all my maps get resized to a much lower res .
I can’t find the option that controls this .
Place I’ve already checked :
Mesh details - lighting - orerridden light map res ( unchecked)
Build - Lighting info - Lightmap res adjustmant - is 100%

To confirm this the lightmap density view shows me all blue .

**The strange thing is that if then i check and uncheck the override lighmap res in the mesh details goes back to the correct assigned resolution, until I rebake the light again and everything gets reset to low res maps again **

I hope is not a bug
