Adding the different Balbooa Form tag to a product in e-commerce Gridbox

I am preparing a catalog of personalized products for which I would like to assign a different Balbooa Form depending on the product version. For this purpose, I created an additional Custom Field in which I enter the tag of the proper form, for example

in the product edition. On the front page of the product the form displays correctly. The problem arises in re-editing the product on the backend. As you can see in the attached screen shot in the custom field where I entered the Balbooa form tag earlier, it loads the form as on the front page. I would like the field to still show the tag itself in the format

after saving changes. So currently I have to remember to retype the tag every time I edit the product. I would like to fix this somehow, please help with this issue.
