Trivia Certificate Error

After taking a Trivia Quiz, the results show correctly on the browser, but the quiz certificate shows the tag "{categoryscore}" instead. See screenshot and certificate of the same results. How can this be fixed? Thank you.

Also, notice that the words CATEGORY and SCORE are not appropriate centered in the table.

Hello,
Please remove this keyword from the certificate template in Quiz settings in backend.

If I do that, then the results will not show up then?
This is how the results are coded, why is it not working for the certificate?

Can you paste the correct code for the Trivia certificates, please.
Thanks.

Hello,
Please check the keywords available alongside the Certificate template in Quiz settings. You will find various keywords to display the score. Each work for the different type of Quiz. {categoryscore} keyword works only if you have chosen category score answer type in Trivia Quiz.

I did. This was the original word in the certificate - I did not change it.
I double-checked it, too.
Please advice.
Thanks.
