How to remove custom metadata field from the alfresco community records manager?

[renato_fritola]

I have created a custom metadata field in the registry manager, I am an administrator, however there is no option to remove the field. How can I do this? I am using version 3.0 of the module.

What is the "Regsitry Manager"? I have never heard of such a feature in Alfresco out-of-the-box and am not aware of an addon by that name. If you are asking about some third party module, you should always include a link to the module's project page / vendor. It is also assumed that you have already asked the developer / vendor of this module for help in whatever forum / support system they provide (e.g. GItHub issues).

Sorry Axel, how I use translator ended up getting the wrong word. 
I meant Alfresco RM - Record Manager. 
I created a custom metadata and marked it as mandatory only after I saw that it was not possible to delete or remove the requirement. I would like to check if there is any way to remove these custom fields as they are impacting on the use of the system.

Thank you!
