Set In and Out Points while Transcript Tab of Text Panel is active

Anyone else struggling with this? I'm going through source media, looking at the transcript... 

I click on a word and hit "I". My in point is set. So far, so good. 

I click on another word where I would like to set my out point, and my in point disappears. 

What I have to do instead, after setting my in point, is click on the source monitor to make it the active panel, then press spacebar to play until I reach the desired out point. This works... but not the way that would be effective utilization of the transcript. 

I'm on a 2021 16-inch MacBook Pro M1, Running version 24.6.3 (build 4).
