This can happen when the form has a custom formatter or other UI Macro implementing some Jelly. You should be able to confirm the issue goes away by removing the custom elements from the form.ResolutionPerform a Script search in [Scripts - Background] Module for the jvar_XYZ name. It should return all the records referencing this in script. The user likely has a Jelly syntax or processing error in relation to this variable they need to refactor in order to resolve the issue.
