Renogy Solar Charge Controller Shows 'FUL' when battery is not actually charged

I have 2 Renogy Solar Suitcases which each have their own Voyager PWM charge controller which I have connected in parallel to my AGM batteries via SAE cable. I have noticed that even if my AGM's are drained down to 30% SOC, when the sun comes up and hits the panels, one of the panels/charge controllers will show that it is charging normally while the other charge controller will show that the battery is full (PWM reads 'FUL').
Any recommendations on why this might be and if there is a way to utilize both panels to charge the battery faster? Would it help to not run them in parallel, but instead just have 2 separate cables/connectors from each panel to the battery?

Equipment:
Solar Panels: 2 x Renogy 200W 12V Monocrystalline
Batteries: 2 x Pro Guide 27 Deep Cycle AGM 100 AH

I ended up just connecting both panels/charge controllers to the battery via separate SAE ports and that seems to have resolved the problem. Not ideal considering I need to carry multiple solar cables, but I suppose it is what it is.
