Hi @LLu0 it likely has to do with your visitors and whether they’ve accepted cookies, which is why the turnaround solution works (it is based on the page data not the visitor data) wherease the original source info is tied to a contact and thus requires cookie consent in most cases (depending on your policy). I would start by reviewing your cookie policy and run some tests on a page without it enabled to see if you get different results that work in your workflow, then at least you’ll know for sure.
