Unable to remove an old cluster using uninstaller

I am trying to remove an old installation of RecoverPoint for VM using the Uninstaller script. It shows the cluster ID after scanning as "Could not retrieve cluster name" and whenever I try to uninstall, it fails with the errors below:

The following cluster/s will be removed:

|  Cluster ID      |         Cluster Name              |

|0x3870b11a08debd41| Could not retrieve the cluster name|

Are you sure?(y/n)

Uninstall process started...

RecoverPoint clusters uninstall process completed.

Warning: the following operation/s failed during the uninstall process:

Unregister RP cluster from splitter esx.server.com on vCenter 10.x.x.x ,RP cluster: 0x3870b11a08debd41

(same error on 3 additional ESX servers that are in the cluster)

I also pulled this from the log file. Any help would be appreciated:
