Manu buttons not active (Scapeshot Pro)

Hi team, My website https://kaja-antlej.com/ uses Scapeshot Pro and for some reason "About" and "Projects (Selected)" buttons in the manu does not work when accessed from a computer. They however work on Android smartphone. I've recently updated the theme with the new version and the issue still exists. Would you be able to advice what I'm doing wrong. Thank you. Cheers, Kaja
