Could you please contact the support team for this ? It is unclear to me, but your gigs have certain labels which are probably the cause for no orders. Yet, you have good success score in 2 gigs.
You have 3 gigs on hold and 1 is suspended (look in denied tab) yesterday. I guess that after 24-48h you will have a chance to add another one. Wait for the support team to answer your ticket.
It could be that if after some time the impressions didn't lead to many clicks/orders, the algorithm doesn't "favourise" your gig that much.
Try modifying gig pictures/price/description.
You won't lose your gigs if you don't do anything. On the other hand, if you delete a gig, you won't be able to add a new one until you delete gigs so you get to the number of 3 gigs.
