BeBuilder White screen / Trouble saving responsive column settings wraps for Query Loop

Hello,

We're having a problem and hope you can help. We're not sure if they're related.

We have a site with a number of pages containing a Query Loop Wrap using {featured_image} for Slides.

The problems we're having are

1)The Wrap => Style => Columns settings appear to be required for all responsive views (which is different from other BeBuilder responsive behavior). When we set them, they are not being saved. Usually when setting a desktop value that value is carried through to smaller screens unless another value is specifically entered. For example, originally our setting on this page were 4/ / /2. For Laptop & table only 1 image was displayed , not the expected 4. https://hci-steel-buildings.websitepro-staging.com/cold-form/

2)For some pages when selecting "Edit with BeBuilder" a white page appears. Re-rendering Builder data will usually solve the problem. Noticed that pages where above column settings not being saved seem to be pages with white screen, not sure always. Was able to 'reach' BeBuilder' on a white screen page by 'Edit Page' with WordPress editor then selecting "Edit with BeBuilder"

A staging site has been specifically set up if you'd like to investigate/experiment. We will reset when complete.

Also, we've noticed recently many more situations where "Edit with BeBuilder" results in white screen. Re-rendering Builder data will usually solve the problem.

Thank you for your help,

Terry
