Visualize Library multi layer issue

my issue is in elastic for seim training.
I’m currently working on Lab 5.3: Lens Visualizations - Multi-Layer Date Histogram in the Elastic training portal, and I’ve run into an issue that’s preventing me from progressing.

Whenever I try to add a second layer using the ecs-suricata-* index (with the first layer being ecs-zeek-*), the Kibana page logs me out unexpectedly. I’ve tried multiple times, but it keeps happening.

This is blocking me from completing the lab, and unfortunately, there are challenges that depend on this lab, so I’m currently stuck.

Could you please assist me with this issue? Let me know if you need any further details.
i noticed that whenever i changed the data view i loggedout from the platform.
