Blue smart 12/30 charger voltage/current spikes

I have a 12/30 3 output blue smart charger that’s hooked up to my leisure and starter batteries in my campervan.
After a couple of days away I plugged in the charger and I’m seeing this spikes in the charging voltage that I’ve not seen before.

Is it anything to worry about? What’s causing them?

Given that the "spikes" are barely 0.1V, I wouldn't be concerned about it. Do you have any kind of load running while you're charging?

No, no load. I’ve disconnected everything to be sure.

It was spiking much more at first, going from 0 to 30amps and then instantly back to zero.
