unread messages noy showing

Where are they shown as unread messages for you to read? <img src=https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2026-10-10-01-07-38-025116.png> <img src=https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2026-10-10-01-07-51-e20b3f.png> The images shown above are of the exact same folder. On the left we have a number of sub folders showing. In the one on the right is a collapsed view of those folders, but the unread unread count is added to the parent folder and it is shown in the list as a coloured outline and coloured text. On the full view that button is the coloured thing, not the text. Is the folder containing the unread emails perhaps collapsed?
