VRM PV-Inverter power flow bug?

Hi, Today i noticed a bit of a bug? (i think) on vrm when pv inverter is pusing power to the multiplus and exporting. I attached 2 videos with the problem one is with ac loads around 50W and the other one is below 30W.

When the load it above 30W the animation from inverter is going the way to the AC Loads and including the pv inverter. When the ac loads are below 30W then the animation is gone and only pv inverter animation is there and not going to the loads or the inverter.


Shouldn't the inverter animation be inputting power to the output when the pv inverter is exporting?


With nearly no ac loads This is with a bit of ac loads

This is the multiplus data on the venus console

I believe there may be a lower limit (coded) of ~30W for the animation dots to show current flow? I know that happens between MPPT charger to battery (for example).
