Custom fields don't distinguish "interface" and "vminterface"

NetBox version

v2.11 beta (beta.netbox.dev)

Python version

3.7

Steps to Reproduce

1. Create a custom field on DCIM > Interface
2. Create a custom field on Virtualization > Interface
3. View the list of custom fields

Expected Behavior

You should be able to distinguish which custom fields are on "interface" and which are on "vminterface"

Observed Behavior

Both are displayed as "interface" - you have to edit each one to see what it's attached to.

Screenshot:

The fields named "VM xxx" are actually on Virtualization > Interface

Of course, for this application I did it wrongly. I should have created a single custom field which relates to both interface and vminterface. But the issue about distinguishing the two types of "interface" still applies:
