Home page – columns not stacking

Hello, I’ve finally found a theme I love with ExS Theme – thank you!

I’m staging my new site, getting ready for relaunch and I think I’m nearly ready. One small but persistent issue keeps recurring for me on mobile testing:

I’m using the main Pro Version.

Issue: My home page uses two blocks with columns that intermittently stop stacking when I’m making changes to the site (not necessarily making changes to the home page when it stops working).

Home page issue areas:
1) First is three columns with text over and clickable buttons underneath.
2) Second is four columns with images and text centered underneath.

I’ve tried “edit page” in the WP editor to toggle the switch to stack for mobile. I’ve tried turning that toggle off and looking for options in the Theme Customizer but I’m not sure which is controlling this.

I appreciate any help or direction you can provide.
