Multiplus-2 2x120 showing -327.7A on AC Out L2

I’ve got a Multiplus-2 12/3000/2x120V in an RV, and the unit is in inverting mode. I have no loads turned on, and for some reason in the Cerbo-GX details page, I’m seeing -327.7A on L2. Should be impossible, right? I am certain there is NOT 300+A flowing
