Unable to add fields in form designer servicenow.

[Mukesh Khanna P]

I'm trying to add/remove fields from accounts table "Case" view using form designer and form layout. But I'm unable to save the edits made, I'm in correct "customer service" scope, I'm able to add the fields, but when I click save, the error is getting displayed.

This issue is caused in client instance, the OOTB form sections where messed by previous devs who made changes to Accounts table form sections. I'm seeing the OOTB section above the current editable section is blanked out and it is non editable now. Kindly help me to resolve this issue, I've attached the image of the error shown while saving the form designer.

@Mukesh Khanna P This issue is occurring because one of your form section is not having a valid title. The best way to address this issue is to revert the form layout to a more stable version (or the OOTB version) and then make the changes in the form layout.

You can use the following steps to restore the previous layout.

 Hope this helps.

The main problem is the sys_ui_section record update versions are shown empty. I'm not able to revert to the OOTB section. It looks like entire form layout sections for accounts table is messed up, is there any way to revert the form layout section in table level?
