Grayed out layers and layer painting selection

I’m new to Nomad Sculpt and I’ve been using it as a at home alternative for Zbrush. I just realized after completing the base for my first model that my layers and layer painting selections are grayed out under export for a gITF file. I just downloaded the app on my iPad around a week ago so I think everything is fairly up to date. I don’t know how to fix it.
