Sometimes they do and sometimes they don't. I have noticed this with a specific sequence of uno-choice parameters and I have reproduced a test case for you here:

Notice that when you first load a page the entire cascade works as it should

You can explore other ACTIVITY options which propagate updates to the MESSAGE which correctly propagate updates to the PLACES_FOR_ACTIVITY (which just references the Dynamic Reference parameter MESSAGE).

Now, we change the MONTH and this updates the MESSAGE. However, the PLACES_FOR_ACTIVITY are now not updated correctly (still showing the previous values)

However, if you continue to select an ACTIVITY, updates again work. So it is the MESSAGE change cascaded from the MONTH parameter that does not cascade to PLACES_FOR_ACTIVITY
