5.6.2 lightmapping HELP!!

I have been using lightmaps for some years now.
But suddenly it seems my lightmaps are way over exposed in 5.6.2.
Like the lighting is being multiplied by magnitudes, totally unusable.

I would include screen captures but there does not seem to be a way to do that on the forum anymore. At least I can’t find it.

If you can point me to some relevant tutorial or post with an answer I would appreciate the help.
Thanks.

I have solved my problem.
Using Area Lights and also all Point Lights are now set to Bake and not Mixed.
