Bubbles in grey resin causing sensor error

Bubbles in grey resin causing sensor error. Hopeful that form labs can come up with solution.

Doing a long print with grey resin causes bubbles to form in back of tray. This causes a sensor error about the amount of resin in the tray. Hopefully, a new form 2 will have at least two sensors in which to detect resin level in tray at different locations or come out with a “surfactant like” liquid to add to the resin so as to decrease the surface tension. I have never experienced this with surgical guide resin…maybe because it is clear?

I notice a lot of froth too, when I print in grey.
