Time/Duration column blank for AAC files

Hello, I’m a new user. My Time column shows dashes when I browse a folder of AAC files. I can use the timeline duration display, but it would be helpful to have the general Time/duration shown. It works with WAV files. I searched the forums to no avail. Any suggestions?

Also, is there a way to vertically zoom waveform displays? I saw a forum post on this but no answers.

Thank you!

That’s a gap in the feature, originally we didn’t have AAC files. It’s faster for scrolling to not read the inner data of time in the sound.
