In-Out Markers Not Working for Exporting

I need to precisely cut audio files and Premiere was the only convenient tool at the moment. I've attached a screenshot below to illustate the problem:

A1 is the source file that I'm working off of (it is so quite that the waveform is invisible). A2-A5 are various exports based on various settings in the "Range" export option. Previously, if the "Source In-Out" range was selected, then the resulting export would fit perfectly between the In-Out Markers. However, now, there's two empty frames at the beginning and 16 empty frames at the end.

Am I losing my mind? Am I forgetting some essential setting that is doing this? Or did Adobe try to push out an update before the end of the year at the expense of their users and their software's functionality?
