BUG: Crossfades don't transfer over from Premiere properly

In premiere, I insert room tone between voiceover bytes in order to smooth out the voiceover and make the edits sound natural. (this is a common practice in industry). I crossfade these chunks of roomtone over a duration of 2 or 3 frames. This is very easy to do quickly in Premiere, selecting all of the transitions and using the keyboard shortcut. However, these crossfades change when I bring the sequence over to Audition for the soundmix. (I'm sending it over from Premiere via Edit -> Edit sequence in Audition). The crossfades become fade-outs that bump up against each other. Obviously this is not ideal, and I have to go through and adjust them one-by-one over the duration of the entire film.
See attached screenshot: the top track is how they get translated in Audition, and the bottom track is how they should appear.

Note: This has not been an issue in the past. This has always been a part of my workflow and just recently started happening. Not sure if the problem is in Audition or Premiere... Thanks in advance for addressing this huge inconvenience!
