ILMT integration import is not fetching all the needed data.One reason could be that the import is running through a Mid server that does not have access to the ILMT. This is because the specified capabilities/applications in ILMT connection are not being honoured in the Mid server auto-selection process.
This problem has been fixed. If you are able to upgrade, review the Fixed In section to determine the latest version with a permanent fix your instance can be upgraded to.
The workaround was to exclude the ILMT IPAddress from non ILMT MID servers until being able to upgrade.
