BUG: Grasshopper Preview Conflict

For some reason the Preview component only renders the first Preview component out of two different Preview components.

Fig. Only the door frame should be brownish while the door itself should be white.

Using latest SRC (7.5.21082.11001, 2021-03-23)

I think this problem started with R7.5 (?)

The problems seems to be isolated to Rendered mode only, all other modes seems ok. (tested with all extra plugins uninstalled).
