Enriched Lineages in Overview do not show up in the Perturbation Effects Tab

When I search for a gene in the Enriched Lineages in the Overview tab I see some cancer types that then, when I click in the Perturbation Effects Tab do not show up.Why is that? Is there another way to explore those enriched lineages? Thanks.

The only thing that comes to mind immediately is wondering if you are looking at a different dataset on the Perturbation Effects Tab, however, that seems unlikely.

Would you be able to share a particular example so that I can investigate further?

Thanks,
Phil
