Exporting historical data to text file with MAX misses columns of data?

I am using Labview 7.1 with DSC module 7.1 and wants to export data to either excel format or .txt.

I have tried this with the historical data export in MAX, and also programmatically with the "write traces to spreadsheet file.vi" available in the DSC module. All my tags in my tag engine file (*.scf) are defined to log data and events. Both the update tag engine deadband and the update database are set to 0 %.

My exported excel or text file seems reasonalbe except that some columns of data are missing. I dont understand
why data from these tags are not in the exported files since they have the same setup in the (.scf) as other tags which are okay exported?

All defined tags can be seen using the NI hypertrend or MAX. Also the ones that are not correctly exported to file.

Appreciate comments on this.

Best regards,
Ingvald Bardsen
