Default WAV & MP3 bounces different lengths?

Looking for some help please as a long term Pro Tools user with a new problem?

When I bounce to disk using the timeline selection, if I create a stereo WAV & an MP3, the WAV is the correct length & matches the timeline selection in the edit page, the MP3 though, is a couple of seconds shorter & the end of the bounce is truncated.

I have this problem on a MacPro M1 Max with 32 GB RAM running the latest version of PT. I've replicated the problem on a M2 Macmini today but have never experienced this on older versions of PT on Intel Macs where the MP3 bounces are the expected & correct length. (These are podcasts usually around 50 - 60 mins in duration.)

Anyone else experiencing this? Any fixes? I have completely uninstalled Pro Tools & reinstalled but this didn't fix the issue.

Thanks.

As a test, take the Wave file and use the free www.shutterencoder.com to make an MP3 from it. Same issue?

That's an odd one. Are you doing an online or offline bounce, and do you get the same results with both?
