This may be a bug but i thought maybe it's part of the fiverr algorithm

I had about 15 buyers requests before I had completed my first order, after completing my first order all the requests has disappeared. it’s been a day like this and no new Buyers requests have appeared.

I think you need to refresh the browser and check again. If no, also check your Gig categories selected well in gig settings. If everything ok, may be you need to wait, sometime this happens for bugs, they will fix soon. Best of luck.
