• If you follow the disassembly instructions on this page https://www.norvil.net/pedal/service/shi¬≠manosti/duraace9sti/strip.php
    I think a problem like that would become obvious in the attached picture. Possibly damage to one of the teeth that hold the shifter in gear, or just crud buildup.

    also I wouldn't try any of this without spraying a decent amount of wd40 down the cable hole and give it a couple days to break down crud, that could potentially fix it without dissassembly.

    happy to lend my ground down spanner if it helps.
