Bad diodes?

I have 3 separate systems connected to a 48v battery system at home.

I noticed one(#2) charger's PV voltage didn't go down to "0" at night a couple of months ago, and now another one(#3) started the same behavior. The last one(#1) behaves fine.

Do those indicate fried diodes?

Is it okay to operate them as they are? I haven't noticed any other error or notification from the Victron, VRM system.

Thanks in advance.

Those 3 charge controllers are connected parallel to the 400a 48v busbar. I use the smart shunt and the GX unit for communication.
