July 4th 2020 all grades question

For the July 4th all grades question, it asked for palindromes using only 3 and 0s and under 5 integers. However, I don’t agree with the answer 10, since 0 is also a palindrome, so that  would make the answer 11.

The problem specifically asks for positive palindromes.
