You can assign multiple flow properties to any flow (open the flow and click the 'Flow Properties' tab) In this case, if the only flow property is volume you can not switch it to kg. openLCA does not know what the appropriate conversion would be, you would need to tell it.

You could either add a mass flow property to each flow, or perhaps more easily would be to convert the value yourself from kg to m3

Too add to this, if you need to convert the units and add them, you need to go into the flow property, add the conversion factor, switch that to the reference unit, and save. It will not auto update if you already have the flow in your process, you will need to remove and readd it to your process.
