Hi ITC. Thanks for the details and the screenshot.
I cannot replicate your issue. Here’s my screenshot, using the front-end form from our Community Events add-on, which is what I’m guessing you’re referring to. Notice there are more than 9 categories.
Please know that we do not provide support here for non-registered forum users. If you’ve purchased one of the paid add-ons, please post your issue in the appropriate forum category (not in pre-sales like this ticket).
If your issue is instead with the free version of the core plugin, you can post at the WordPress.org forum. Please pay attention to the sticky/highlighted posts before creating a new ticket there.
I hope this information helps! 🙂
