Cause:
This is expected behavior.
DXP files created using the Signals One platform are not compatible with the on-premises Spotfire Desktop Client.

Resolution:
Use one of the following approaches:
Recommended: Open the DXP file using the Signals One client.
If you need to analyze the data in on-premises Spotfire, export the data from Signals One in a supported format (e.g., CSV, SBDF) and then import it into the Spotfire Desktop Client.
