Ive created a new VAT category. But when I try t import bills using that new category, it only shows the original categories (exempt, Zero rated and standard)

I want to ensure this is taken care of, @usernestor-ale.

Usually, this error occurs when there's too much cache in your browser. To fix this, let's perform some troubleshooting steps. Let's start by accessing your QuickBooks (QBO) account using a private browser. The following are the shortcut keys you can use:

• Google Chrome: press Ctrl + Shift + N 
• Mozilla Firefox and Microsoft Edge: press Ctrl + Shift + P
• Safari: press Command + Shift + N

Once done, import your bills again using the new category. If this works, let's clear the cache and cookies of your browser. If not, you can use another supported browser. Possible that your current browser may have a temporary issue with QuickBooks.

Also, I encourage checking our Help articles page to learn some tips and tricks in managing your QBO account. From there, you can read great articles that can guide you through the steps by steps process.
