Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
Using AWS OpenSearch :
- Version Info : OpenSearch 2.19
- Service software version : OpenSearch_2_19_R20260626 (latest)
Opensearch Dashboard : 3.5
Describe the issue: Since upgrading the service software version from OpenSearch_2_19_R20251112-P1 to OpenSearch_2_19_R20260626, the Opensearch Dashboard version went to 3.5 resulting in duplicate labels in all of our TSVB.
Configuration: Upgrading to the latest service software version seems to be mandatory and to be done before end of month/august 2026, but the opensearch dashboard is provided by AWS and we have no way (i think) to make it stay in 2.19 as we do not manage it ourselves.
