In order for audio elements to be displayed in the right places in POST, your different automation categories/types will need to be defined on the Categories page.
Futuri's installation team will typically place some common categories in the right positions for you, but you may want to check this from time to time for accuracy / completeness.
On the Categories page, you can see which automation types are assigned to which categories, and you can drag unassigned types to the correct place.
There are several configuration options when editing a category, but most of them should only be changed under the advice of Futuri VIP Support. You can feel free to change the color to your liking, though.
If needed, you can also create new categories using the Create New button at the top right corner of the page.
