adding a watermark in LR after using Luminar for editing

[marilynlillard]

I am struggling with adding a watermark in LR after taking my photo to Luminar 4, adding a "look" and returning to LR to publish.  It grays out the watermark availability.  Does anyone know if it has anything to do with using a look in Luminar 4?
