When Editing (creating, modifying, saving with a different name, etc..) a Performance Dashboard on the Performance Perspective Workspace of OBM UI, it is found that list of current available Dashboards are not in sync when pointing separately to a different Gateways' URL for visualization.

Environment

OBM (Operations Bridge Manager), version 24.2, on Linux OS based installations.
Distributed architecture (2 DPS in High Availability + 2 or more GWs)

Situation

After accessing on the OBM User Interface with whatever user, admin included, and after editing a Performance Dashboard on the Performance Perspective Workspace of OBM UI the list of current available Dashboards are not in sync, when pointing separately to a different Gateways' URL for visualization. 
This is the case of a new Performance Dashboard created, or saved with different name, or modified and saved with same name, etc.

Example steps:

• Login to the OBM UI as admin user pointing to the URL of Gateway1 FQDN name, as for example:
  https://<gw1_fqdn>/topaz/login.jsp
  and then after going to the Performance Perspective, modify the name of an already listed Performance Dashboard:

Here for example the System_CPU_Bottleneck Dashboard has been Saved as System_CPU_Bottleneck_cachetest under the                                  Standard_Dashboards Category.

• Pointing now with the Browser to the URL of the second gateway:
  https://<gw2_fqdn>/topaz/login.jsp
  and going to the same Performance Perspective Workspace, it can be seen that the list of available Standard Dashboards are not the same as above, and the new Performance Dashboard created is missing from the list:
