Alfen Eve pro - not all values read

[JohanDonne]

I have a problem with the combination of HA OCPP with an Alfen Eve charger.
They connect fine but not all the selected MeterValuesSampledData are received from the charger:

The charger accepts the keys from HA-OCPP:

`

But afterwards only one single key is exchanged:

`

What could be the reason for this behaviour?

Update: issue resolved itself. Next day when I looked, all values where received (don't know what solved it, tough).
