Ladybug radiation sun path study- grid not showing on referenced geometry

Hi everyone, another problem I have with Ladybug and looking for help.
I created a simple definition for sun radiation study. It works fine, but the grid element in the LB Direct Sun Hours isn’t showing. Instead I get this weird texture on my referenced geometry.

Any ideas?
