Reply To: popup contact forms falling out of popup button

An issue I noticed after doing the theme update, is that on a couple of my pages with popup contact forms, when I go to that page (front end) the contact form is visible though only the button should be visible. After I hit F5 it ‘fixes’ itself and displays how it should. Please see screenshot. I thought this was fixed but it happened again. BUT it’s currently behaving as it should on other computer so I don’t know if it’s just my computer somehow.
