Hello @vickieito
Thank you very much for taking the time to reply. I checked out the links you've shared and I think I understand now. The last delivery which was 2 days ago, was for a different gig, that is https://www.fiverr.com/share/GomoBL (I think the last delivery provides the date of the most recent delivery out of all gigs). Therefore, like I said I haven't received any orders for this particular gig on dental/medical and health-related articles.
Thank you once again.
Best Regards, Team FMW
