Setup:

Main switch is TL-SG2210MP v1.0

Connected to this switch are 2 additional switches, both ES205GP v1.0 (theater switch for this example, also office switch)

All clients are successfully being assigned IP addresses

The issue is purely visual

On the OC300 controller, it is not showing the IP address of any Client connected to the "sub" switches, even though they are assigned

Clients connected directly to the "main" switch DO show their IP address

Is there a setting I'm missing?

I've just done a factory reset on all my equipment which did NOT fix this issue

"sub" switch not showing IP addresses, even though they ARE assigned

Same screen, but "main" switch SHOWS IP addresses

Example that "main" switch correctly displays IP addresses, while "sub" switches do not:
