Lynx Smart BMS 1000 limiting charging before absorption hits

I have a system using the Victron LFP Smart 25.6/200 batteries (20x), 250/100 VE.CAN MPPTs (14x) and 6x MultiPlus 24/3000 units. There is a Cerbo GX and a Lynx Smart BMS 1000. ESS is configured.

The issue am seeing a couple days in a row now is that the charging form solar is stalling out at 27.0v (the float voltage) and not continuing up to 28.4v (the "charged" absorption level) like it would in normal Bulk charging (everything is of course in external control due to ESS and DVCC).

What is the needed setup so that each morning, as the sun comes up, the system will charge full speed up to 28.4v without me having to try to prod it forward past 27v.

I suspect this is absolutely something related to the Lynx Smart BMS and DVCC that is very much acting differently from how the system behaved previously with the ve.bus bms and DVCC.

Thanks!

I have pictures from VRM and settings showing all of this, but the interface here keeps failing when I attempt to upload them

Unsure what I did that made the difference, but it seems like CVL is now where it should be and the system is working as expected for the last few days without any intervention.
