Hello,

First of all thanks for choosing our Theme, we are glad to be you in the WoodMart WordPress family :-).

I saw the screenshot you attached visited the URL you provided. To change the order of categories menu items you need to Go to Appearance >> Menus >> Edit Categories Menu.

And you can change the order according to your requirements by simple drag and drop.

After changing the order of the categories are still displayed in Alphabetical order, then please share admin panel login details of the website to check it myself and help you out accordingly.

Best Regards.
