Blue Smart 12/30 IP22 skipping bulk charge

Victron Lifepo4 200Ah is currently at 3.13V per cell. Expected behaviour of the charger after switching it on: It should bulk charge the battery (LiIon-Mode enabled) with up to 30A and switch to absorption charge after the battery ist almost charged completely.

What the blue smart device does instead: It bulk charges for ~2s (yes, seconds...) and switches immediately to absorption charge for the next 2 hours with ~6A (decreasing over time). So the battery is never charged to its full capacity...

All parameters in victron connect app seem to be correct. 'Charged voltage' in BMS ist set to 14.0V, blue smart charges with 14.2V. Did I get something wrong? Any suggestion are welcome.
