Real time note iinput - Metronome defaults to smallest subdivision

I've been searching all over for this bug/option but can't find anyone else who has this problem. When I'm using real time auto MIDI note input, if I use 16th as my smallest subdivision, the metronome stops playing in the time signature of the piece and instead plays 16th notes which prevents note input. It also slows down to 1/4 (1/4 of a 1/4 note) of the tempo of the piece. Can't figure out if this is just an option I accidentally set somewhere or a bug. Anyone come across this and have a workaround?
Thanks in advance.
