My Database type and version is: Mysql

Your problem
My problem is: Form not correcly updated
More info: I have a a select group with dog breeds saved in custom contact field. I have removed and added some dog breeds, so i expect the new form to load correctly. But it still a wrong one. I shows all custom fields instead of the ones i have selected. Just in the preview mode it shows the right one. Even when i analyse the manual code it has wrong dog breeds. It shows all breeds possible from the custom field. How to solve?
Use assigned contact/company field’s list choices is set to NO

These errors are showing in the log: not important

Steps I have tried to fix the problem: clear cloudflare cache and mautic cache a few times

Just to make sure - did you test the “Rebuild Cache” function from the form bulk edit menu?
