3.10

Steps to Reproduce

The issue seems to be returning here. When importing the prefixes bulk below I get the following error:

Record 1 vlan: "1" is not a unique value for this field; multiple objects were found

prefix;status;vlan_site;vlan;scope_type;scope_id;description
10.11.0.0/22;active;LOC02-MGMT;1;dcim.site;5;LOC02-MGMT

We have multiple sites with the same VLAN id, we re-use them same as the existing issue. However, it doesn't seem to be using the field 'vlan_site' to check whether the VLAN is unique for this one.

Expected Behavior

Import the prefixes and assign VLAN based on VLAN site and not only ID.

Observed Behavior

Unique constraint error.
