why i see this

Hi,

I suppose that this means that the "specialty pizza" category is under the "default tax category" for some reason.
I would recommend to first check your categories in the menu Products>Categories.

Hello,

Can you provide a screenshot of your category tree, I mean this :

Hi,

Try clicking on the "rebuild" button of the categories listing.
If that doesn't help, edit the "specialty pizza" category, make sure that its parent category is the "product category" category and save it once. Then, click on the rebuild button and check if that helps.

If not, I'm afraid we would need a backend access in order to check on the situation directly.
