Not that upgrading is enough to solve the problem, but yes there have been multiple PsychoPy bugfix releases in the last few weeks! The latest version is 2020.2.10. I believe your project may have been initially created using 2020.2.6. As it happens, earlier versions have no notion of targeting a later one and that I believe is the reason 2020.2.7, 2.8, or 2.9 also seem to be missing from the dropdown menu in the screenshots.
