New pool - questions on sense and dispense

We just wrapped our pool build that ended on poor terms with our contractor. He basically dumped salt, turned it on, and left.
Hayward equipment:
Super pump vs 700
Aquarite Pro (AQR15-PRO)
t-cell 15
Sense and dispense with muriatic acid
Heatpro heat pump
Although we still have way too much salt (need to deal with this today), I believe I have everything else well in balance. The issue I am now running into is tons of air bubbles from the returns. While diagnosing, I discovered I am only getting bubbles when the sense and dispense unit is running. I then noticed that the probe cell is plumbed directly into the pump's drain ports, one of which is loose and probably the air culprit.

After lots of googling, it seems like the probe cell should never be plumbed directly into the pump but rather into the pipe. Can anyone confirm this for me and have any recommendation on how to tighten the connection to fix the air? Should I get someone out to plumb it properly?

I am new to all of this so any help is greatly appreciated! I will try to attach some pictures when I am home.

Welcome! There will be bubbles coming out of the returns wherever the unit is making chlorine, that’s just part of the process. Need someone else to comment on the other stuff.
