Forms with visibility rules enabled are not working

Hey guys,

So we tested two forms on the same landing page.

Both forms were basically identical, except for one big difference.

One form had visibility rules enabled, and one form did not.

The form with the visibility rules enabled is giving us issues. When the user clicks "submit", they are not taken to a thank you page.

When the user clicks "submit" on the form without the visibility rules, they are transferred to a thank you page as normal.

Anyone know why the form with visibility rule would behaving differently? Anyone run into this before?
