We've created a custom field in table product of type checkbox with 3 checkbox values - value_a, value_b, value_c. We set the display to back-end form (but we've also tried setting it to front-end also with no change to the issue).

We then created a custom field in table product of type custom text containing some html. We set the field display to front-end and back-end form. We set the 'display limited to' to the custom checkbox field and 'equal to' value_a checked.

(The plan was to also have additional custom text fields that display based on the checkbox field value_b being checked and another based on value_c being checked so that a product could have none, 1, 2 or all of the custom text fields displayed based on the checks for the checkbox field.)

But, regardless of the value(s), or lack there of, of the checkbox field, the custom text field always displays on the frontend.

In troubleshooting we also tried to instead create a custom boolean field and set the custom text field display limited to the custom boolean field value being 'yes'. Changing the boolean field value on a product also did not affect whether the custom text field displayed on the frontend. It always displayed whether the boolean was no or yes.
