I tried adding the rocket silo's "low-density-structure" to be monitored
and got this
Notice:
Error while running event production monitor:on_gui_click(ID 1) _production monitor _/control.lua:541: attempt to index local 'calc' (a nil value)
I did notice that at the precise moment that I dropped the item on the '+' it replaced all the fluids being monitored right before giving the error.
Haven't tried it with other rocket ingredients or other stuff, but I will and report back.

EDIT: I tried with other items and I get the same error.
