Multiple entries for package name in Orchestartor after orchestrator-shared drive mapping

Scenario:

Orchestrator is normally mapped “~/NuGetPackages” in the server where it is installed . We have changed this path to a shared drive location by updating packages path in the Web.config file.
Under ‘View Packages’ section in Orchestrator, we can see single entry for a package name and when we select versions we are able to see all the versions for that package but after this change I can see multiple entries for the same package name and all of them has same number versions.
When we rolled back the change, Orchestrator is behaving as expected ie. single entry for a package name.

NOTE: This change was part of HA setup.
Both “~/NuGetPackages” and shared drive location has same packages.

Steps to reproduce: As mentioned above.

Current Behavior: Multiple entries for a package name after the change.

Expected Behavior: Single entry for a package name after the change.

Studio/Robot/Orchestrator Version: 2016.2.6274

Last stable behavior: NA
Last stable version:NA
OS Version: NA
