How to prevent Gravity Form submission from overwriting existing data?

My content download form fields vary. Unfortunately, previously collected information is being overwritten as “blank”. For example, form A includes name, email and company. Form B included name, email and industry (no company field). When Form B is submitted the company field is updated to “blank”. How do I prevent existing data from being overwritten?

This sounds like a good issue for a support ticket. Can you open a support ticket here please:
