Unable to access row/module settings on single page

Hello,

On one of my website’s pages, and only one, I am unable to access the settings of modules/rows in Beaver Builder mode.

When I double click the row/module no settings window opens up, nor does one when I click their tool icon.

Interestingly, when I add a new row/module its settings window pops up right away, and after publishing the page and re-accessing Beaver Builder mode I can access the settings of the newly added row/module, but not of those that already existed.

Any help would be hugely appreciated. I am very new to all of this!

Thanks,
Sam
