Hi @Living Gems A,
If this is a question about Google My Business, their forum will be much better able to help you!
This guide to Google My Business Categories is a great place to start for help with this.
Apparently Google releases Google My Business categories by country - is it possible the other businesses listing that category are in another country? Here's a list of categories by language that I found in a Google Support article, Guidelines for representing your business on Google.
In the article mentioned above, Google says you should focus on adding the most specific categories and they'll fill in the rest.
I hope that helps,
