Conversion reporting delay

Hey guys, I have a quick question.

Yesterday I saw that one of the products I promote converted multiple times, but on my CPA page I see only 1 conversion.
It's pretty impossible for somebody to visit my conversion tracking pixel without paying for the CPA product I'm promoting.
It can't be some kind of false click or whatever because this offer converts on sale. Also this lead isn't under reversed lead.

Since my AM is not online I decided to ask here. So do you guys have any ideas what's up?

it can be just an update in the stats, or you got some invalid leads, is it pps or ppl?

As I said above it's a sale. And usually this update takes like 5 minutes not 12+ hours :/
