Renaming of custom fields not visible to all users

Renaming of custom fields not visible to all users

Hello, 

I've got a problem and I don't know if this is a bug. 

We are using Zoho CRM within Zoho One with different users. We noticed an issue with Zoho CRM. When I rename custom fields fields the old name will still be visible to other users, even when the custom field is renamed. 

We do not have different layouts in the module (only one layout) and I have already checked the access rights. All users who have noticed the problem have admin access. 

Could you please help me with this issue? 

Thanks a lot, M.
