I'm well aware of that, the feature was mapped some time ago. staffordstafford has since mapped it for a second time, so it now shows up twice on the cycle layers, and one needs removing.

I'm not seeing that, cycleway:left=track and cycleway:right=track have been used appropriately so the cycle map layer and CyclOSM are rendering it correctly.

This is already mapped using the cycleway=track tag. One of them needs removing
