LiFePO4 solar charging confusion

[Orca]

Can anyone explain why the DCC50S is charging my LiFePO4 battery at 14.4 volts, all day, when it's already fully charged.
It starts charging in Bulk mode when the sun comes up then, mid-morning, switches to Boost mode and charges for the rest of the day at 14.4v (0.5 - 0.7A)
The van's just sitting on the drive - no EHU connected, so only charging via the solar panel.
Is this OK for the battery?
Should I let the battery discharge a bit (90%) before re-charging (maybe disconnect solar for a day or two)?
Thanks

I fitted isolator switches between the solar panel and the charge controller, and also between the charge controller and the battery, so everything could be disconnected easily if Im not using the van for a while. Might be something worth looking into?

Also, I don't know what battery you've got, but see the image below. (Mine is lifepo4). The instructions for storage state the battery should be 30-50% if storing it. Which it kind of is, if it's not being used for a while. Might not be a good idea to constantly charge to 100% when not in use.

I wouldn't overthink it, there's no indication that it's misconfigured so just let it do its thing.

If you're really leaving the battery for months on end without touching it, then maybe consider the charge, but short of that I really wouldn't worry.

Got a few screenshots from the app?

I've got a drain of about 0.6 A (camera, tracker and WiFi router) so it drops to about 96% over night.
But then full charged by about 9 a.m.
