Mppt float too early on tail current

I'm using a 150/85 and set 13.85V Bulk with a 6hr fixed absorb time as I often get heavy cloud during the day, and a tail current set to 14A.

On bright full sun days the mppt goes to float very early like at 36A tail.

On dull days, it behaves its self.

I also have a 100/50 that is set up exactly the same settings.

I usually run it together with the 100/50 over VE smart network where they work well until I get a full sunny day and the 150/85 takes us to Float way to early before reaching the tail current limit!

When I turn off the 150/85 and run the 100/50, it does what I want and cuts off when tail reaches 14A.

Why is my 150/85 going to float early??

What happens when you run the 150/85 on its own?

What settings are in the MPPTs?
