Hi there,
I noticed, that when I select a zone to clean and then refresh the page the zone that is in progress does not show up.
It does show up in the Roborock app though.
Roborock S6 MaxV.

Figure: Roborock app - zone in progress is visible

Figure: Home Assistant Roborock Custom Map - zone is not visible after page refresh (or if you view from a different device)
