Check if you have a sub directory called "Settings" into the DIR where you save the recorded images.
All image data is recorded in Settings 'TXT' files into this 'Settings' DIR.
When replaying those Settings 'TXT' files are read and the number and time of sub exposures is displayed.
If you are missing these Settings TXT-files, no exposure data can be displayed.
I remember, when I started with the Infinity, that those Settings files where missing.
But I can't recall what the reason was.
