Error: Some of your fields have duplicated datanames

[poonam279]

Description

A field group attached to a specific Product Category behaves unexpectedly after editing and saving a product in that category. It gives the error message ‘Some of your fields have duplicated databases. Please fix it‘.

I have checked with Version 33.0.8, and it shows the same issue, so it's not a regression.

Step-by-step reproduction instructions

1. Attach a field group to a specific Product Category so that the group applies to all products in that category.
2. Edit a product belonging to this category.
3. Save the product.
4. Now check the product. The field group doesn’t display on this product anymore, and it gives the following error message: ‘Some of your fields have duplicated datanames, please fix it‘.
5. Also, when you check the field group, originally attached to the category, is now also attached to the single product that was edited and saved.
