Substance with two graphs can´t see exposed parameters on sbsar

Explorer ,

Hello, I have a substance file with two substance graphs, one of the graphs I created a pattern but I wanted to combine that pattern with another fabric material sbs I had.

The exposed parameters I made on my "HexTri '' are working fine in the sbsar but the exposed parameters on the base fabric aren't visible even though I have the "base fabric" package exposed in sbsar.

Any ideas what might be failing? Thank you.
