Chord extensions broken in one of my files only

So I’ve been experimenting working with HookPad for some time now. But I just ran into an issue that is only affecting one of my projects.

In that particular project, the chord properties are malfunctioning. I can select triads and 7th chords and inversions work, but anything beyond that either doesn’t work or doesn’t give the expected result. 9th, 11th and 13th chords sound exactly like triads (again, in this specific file only). No5 works for any chord that is not a 7th chord. I can’t find any logic behind what works and what doesn’t so I’d appreciate if the staff could look into it.

I tried saving the file, closing the browser and reloading it and the problem is still there. That does not happen if I load any other project.

Did I miss something?

Thanks
