Great game but there is a glitch – Educating Eddie HD - add & subtract exercises for primary school children Review

This is a great game. My son loves it except we have found a glitch. On one of the addition problems, the problem is 6+3 the answer is 9, but it says incorrect. Even my husband tried it to make sure I wasn't reading it wrong.. Just thought you should know.
