Here 2 shows double value

New build on which i have Here2 on Can1 (can2 marked on my board). I know its Can1 because on can 2 i was unable to connect to SLcan1 in order to check settings and potential update but when i plugged on Can2 it connected by pressing SLcan1.
My question is: Why do i get twice the line?

Can it be that i originally connected it to Can2 (which is actually marked can1 on board)?
