Not allowed to put at U0

[Riprock]

NetBox version

v3.6.5

Python version

3.11

Steps to Reproduce

This is all preformed in the UI

1. Create New Rack
2. Create new Device
3. Attempt to assign to to U0 To have device be at the bottom of the rack

Expected Behavior

What I expected is it to place the Device in U0-U3 Not to have a 1U gap as shown in pictures above

Observed Behavior

Error was provided in the interface saying I cant put a device at U0 because it has to be 1 or greater

0 should not be a permitted value for Rack.starting_unit. The bug is not in the placement of the device, but rather in the failure to validate the minimum value for this field.
