Open Distro fixed numerous Kibana Reports bug in 1.13.0 version (
here) but that version it's not yet compatible with Wazuh. The last Wazuh APP version supports Open Distro 1.12.0.
We are working on update the supported Open Distro version.
This is probably an Open Distro related issue. Did they reply back to you? Which version of OpenDistro are you using? I found a similar issue
here and it seems it was fixed in Open Distro 1.13.0.
