@Annelio I would advice using Marketing Channel instance metric to see
how many times a marketing channel was defined in an image request
(either s.t() and s.tl() image calls).From the screenshot, it looks like
eVar32 is not getting captured as expected from the URL for 'SEB Mobile
Apps' marketing channel, that a visitor uses to navigate to your
website. I will recommend pulling a data feed report and reviewing the
pageurl column to see what is actually being captured in that visit.
