Columns inside custom fields' meta_key function are not meeting the global condition after saving the form

[mmarj]

After saving the form, the columns inside custom fields' meta_key function do not meet the global condition. It changes the inside element's meta_key even after saving the form.

How to reproduce:

1. Create a form with columns fields.
2. Drag a custom field like text
3. Change the label; you'll find the meta_key changing respectively upon the label, which is a global case for columns-outside custom fields
4. Save the form
5. Now, change the label of the inside text field again. You will see it's again changing the meta_key upon the label, which should not happen.

Expected behavior:
The columns inside fields' meta_key should not change after saving the form like the columns-outside custom fields.
