EXIF ISO is not recognized

[Russe]

Hi,
I'm new to Photo Mechanic and just evaluating the most recent demo (4.6.1) on a MacBook Pro (Intel) with Mac OS X 10.5.7
I noticed that there are some photos taken with Canon Ixus 40 where the EXIF ISO is not recognized by Photo Mechanic. When opening these pics in Apple's Preview there's the EXIF ISO displayed.
Is this a bug in Photo Mechanic?
Please find attached an example pic.

Thanks for your help. I double checked with iView MediaPro and there's also AUTO displayed. Don't know why Preview show ISO as 50.

One more question, where do you get this EXIF list from?
