Duplicate folders created when rendering from montage

Sometimes - when I set the destination folder for render from an audio montage - a duplicate folder of the same name is created. When setting the destination path it seems sometimes (not every time!) a space is added in the render path before a / and WLB tells me the path isn’t valid until I delete that space. I’m not adding a space in the path - I’m just selecting the desired destination folder that I’ve created prior to render.
It’s at this point it seems a duplicate folder is added to my drive and the rendered file ends up in this duplicate folder. What’s going on here?! I’m on Mac Sonoma 14.1.2

TIA

Maybe you are using the new Contextual folder feature, by mistake?
