Welcome to the community @absinthia
Klaviyo attributes a sale to an email from a campaign/flow if the recipient opens or clicks and purchases within the attribution window (5-day default for emails). The most recent email opened/clicked gets that attribution.
As you are seeing wholesale orders attributed to an email, those contacts must have received that email and opened/clicked/purchased within the attribution window.
You mentioned that you have a separate segment for wholesale contacts. Are you excluding that segment from your campaigns? If they have found their way onto another list/segment you send to, they need to be excluded if that’s what you want to achieve.
Hope that helps.

Thank you! I have selected the wholesale segment to not receive the emails. Let’s see what happens this weekend.
