Standard Dual Core Fibre SFPs connecting to each other across a Carrier who supplies ID's on a Per Core Basis

[jethro66]

I have two End Devices in two different Data Centres (20km Apart) that are connected together using Single Mode Fibre. Each end is dual core terminated into ER Type SFP's. My Carrier provides this service to me with two individual cores, so I'm not using circulators across a single fibre core. There is no magic in between, it's dark fibre end to end, so think of this service as a very long patch lead between two devices :-).... Each fibre core supplied by the Carrier has it's own Circuit ID, and such I need to keep track of all my Circuits in Netbox. I therefore have two Circuits to provide this service.

I am struggling to work out what I'm doing wrong in Netbox to do a Cable Trace End to End. I thought my previous version of Netbox V3.6.1 was the issue, but after we finally upgraded to V4.2.5 this week, same problem which I will now try to illustrate and request assistance with please.

I get a "Path Split!" Error at each end, and consequently don't see the overall path End-2-End. Here's the two separate ends illustrating the issue. I hope it's because I'm just a "newbie" and I'm missing the Captain Obvious, and not some Bug. I have two circuits created "Test A" and "Test B", and I've patched "Termination A" of each circuit to a unique Rear Port on FOBOT A at Site A. "Termination Z" of each circuit is patched to a unique Rear Port on FOBOT B at Site B.

I can go into each Circuit definition and hit the green "Trace" ICON for either "Termination A" and "Termination Z" and it shows me the cable trace for local end only, out to the End Device.
