AO and thikness baking give me black map

[Skav]

Hi everyone,
I have a problem that I don't know how to fix.
On the creation of my substance I was able to bake all maps without any problem.
I had to change my high poly for and updated versions and once I bake all the maps again all the maps are ok
except the AO and Thikness that give me only black map and I don't find a way to fix it and if I play too much with the setting designer crash.
So I was able to bake my thinkness map and AO only one time at the creation of the substance?!

Thanks.

Maybe you have activated the "Match by name" by mistake (and haven't setup your meshes accordingly)?
