Modal is shifting to right

I’m using a modal popup for “read more” links in the first section down (Breathe Page), but they are shifting to the right. I used the same modals on a different page (HVAC Professionals Page) and they look and work fine.

They specifically change when you switch the ‘position’ of the parent element, e.g. ‘modal-pm’, to sticky or fixed. And when you do switch it, it creates the problem on the other page – if the modals work good on the HVAC Professionals page because they are on ‘sticky’ for ‘position’ then the Breathe Page “read more” modals are messed up, and vice versa.

Please help
