The tank capacities in the VRM advanced page are not correct. I have set the capacity of all three of my tanks to 30 gallons. With the preferences in VRM set to display volumes in liters the tank summaries initially show 114 which is the correct value. A few seconds later, the capacity changes to 0.
With the VRM preferences set to gallons, VRM advanced shows 30 gallons briefly for capacity then changes to 0.11 Gal.
All of my tanks are currently empty so don't know if the remaining value is displayed correctly or not.
