polaris pop-up keeps popping out

[mybluepool]

Well the subject line about explains it. one of the holes where the jets fit in has something wrong with it as I have even tried swapping out the jets. any suggestions are welcome because it only takes about 2 or 3 cycles before it pops out.
Thanks

So, the fitting is the problem? All of the heads will stay in place if put into another spot?

Yup. So what can I do, if anything, about that?
