How do you maintain checked items when using multiple multi checkboxes?

When I put three multi checkboxes on my site, clicking anything in the second or third multi checkbox unchecks everything in the first one. I want customers to be able to check whichever items they want. Is there a better way to do this than creating a bunch of individual checkboxes?

In this screenshot, the first column (Multi Checkbox 1) has checked items, but checking anything in the second column will uncheck all items in the first column. This makes it impossible for a customer to check everything they want, unless I do individual checkboxes, which are a chore to place and line up one at at a time.

I think you will have to CODE it.
You surely work with datasets by making connect them with your CBGs (CheckBoxGroups).

As i can see you are also using → SELECTION-TAGS. I would suggest you to generate your own FILTER_ENGINE by CODE → which will be surely not the easiest task.

How will coding keep the checkboxes visually checked?
