[Observium] switch missing interface data

Hi All

not sure if this is a bug or maybe something wrong with our switch?

we added a TP-Link 8 port gigabit switch to monitor as we wanted to see what data we could get

for some reason, observium has listed all interfaces as Ethernet Interface ?

also it appears the vlans are also being found as lans, as well ?

no port 1 port 2 etc

just Ethernet Interface and Vlan ?

what ive also found is on the interfaces page the plans are showing these blue arrows with the ethernet interface name ? never seen it before? any ideas?

attached is screenshots, poller log and discovery log if people what help :)
