Can't set blind to my position using Google Home

I’ve tried the suggestions from

Unfortunately, none of the options work for me – I’ve named my device “middle shade”, and so the commands I’ve tried are “Set middle shade to preset” “Set middle shade to preset mode” (and same wiht “favourite”, and “my”). Google seems to either search the web or say it doesn’t recognize that command. I’ve typed these commands in manually too without any luck.

Is there anything I can try to get Google to recognize the preset/favorite commands? Thanks!
