Auto Submit Not Working

If you go to:
https://www.eastcoastclassics.com/

We default our shop page to show products.
We have Options > Autosubmit = YES
But when you use the filters, you must manually press “FILTER”. Do you have any idea how to get the Autosubmit working so that:

1) The actual called products dynamically and automatically change.
2) Pagination works. I did read the thread on pagination and this is not as important as getting the returned products to update automatically. But perhaps these two items might be related.

Thanks!
