Thank you for the clarification.
Of course, please feel free to update us if there are more details on the issue.
In addition, please try updating Remote Utilities to the 6.12 Beta 1 version and see if this helps to resolve the issue. The 6.12 Beta 1 version is available for the download here
When updating Remote Utilities please make sure to update both Viewer and Host/Agent as the version mismatch might lead to performance issues and some features not working.
Looking forward to your reply.
