Hi, welcome to Fiverr.
If it’s a new gig, there’s a chance that Fiverr hasn’t added your gig to the index yet, so it’s worth giving them some time before it appears. The same applies to new accounts, so there’s a chance it’s just taking some time to get you in there.
I’m not sure if this is me misunderstanding what you’re doing, but if you’re attempting to manually discover your gig in those categories, the listing order of more popular gigs will take priority over yours, as it’s a new gig, so yours would not be present at the forefront of those categories. All in good time though, I’m sure with hard work and good service, you can be a front page gig.
I hope this helps, best of luck.
