Problem with archived trend data

Problem with archived trend data

Hello,
When I visualize some archived data in a trend window, why do some of the tags show values sometimes and not at other times when I am scanning through the data? For example see attached JPEG files s1 and s2. In screenshot s1, the value of the tag DEEPAK1/AS_PID2/MODE can be seen at 11/27/2010 4:05:01PM but in the same trend display, in screenshot s2.jpg, when I move the scan cursor over to 11/27/2010 7:51:09PM, the value for that same tag is not shown.
The archive is a "spontaneous" scanning archive and the archive saving format is "Internal database (*.arx)". I am using v6.22SP0 Build 0.
