Its not Supported to use newer version of data_engine with older version of the product
UIM 8.5.1 SP1
Deploy data_engine 8.50 probe version over data_engine 9.x version
IF the issue persists, then:
Option 1 - This behavior dealing with missing in incompatible database schema , you will have no choice but to roll back to the last DB Backup or do a clean database install
Option 2 - Upgrade the Entire environment to the same Data_engine Version so 9.x
