Can you confirm you just closed the cleaner valve?
I have the same problem. Shared cleaner and curious if closing the valve still allows water flow or maybe it’s not an issue.

Here is the DRAIN (Suction) and OUTPUT photos. I think ultimately the issue is the one I labeled "Spa Center" because I see water coming up center of the spa when in pool mode. I think closing this valve solves the problem. I did also close the vaccuum valve too at the time so could be either.

You have a pressure Side cleaner. The down pipe goes to the pool returns and the Tee junction feeds the booster pump which drives your pool cleaner. I would never turn that blue handle closed.
The center spa pipe refreshes your spa and allows it to spillover to the pool. that blue handle valve can control if you want that feature on or off when in pool mode.
Your cleaner is fighting for volume when the 3 bubblers and fountain are on and the center spa is open. Closing any those will put more water through the pool returns and the cleaner.
Makes sense. Thanks. So when the pool automation goes into freeze mode where it flip/flops between pool only and spa only every 30 minutes, I was seeing that when in Spa mode, the spa will drain back into the pool.
I was thinking that the spa would drain from the spa center feeding during freeze mode. While we havent had a freeze recently, I reproduced the issue even with the spa center feed closed. I believe its the spa drain Jandy valve. When it goes to Spa suction mode then goes back to pool mode, the spa suction never goes closes all the way. I can pull the handle ever so slightly and it moves a tiny bit, then my issue stops.
Either the Jandy valve is bad or the automated controller isnt closing it enough. Any suggestions here?

It could be the gearing on the actuator is worn and not making a full return to the starting position.
A check valve on the spa suction would help prevent that.
It also can be someone at a time messed with the end switch on the actuator to make adjustments and never made sure that in this position it's at full close.
Thank you both for feedback there. Sounds like a check valve would be an easy solution, though require some plumbing work.
@wireform Do you happen know if this particular Jandy would let me take the cover off and adjust the end switch?

I'm not sure which actuator you have but here's one example. If it's not what you have then do a YouTube search for your model #
