Did you already figure out this one?
Thanks for posting this Indre! I am in the same predicament where I would like to reset the filters on a specific dashboard to their original values. There is always the F12 (Revert to Saved) option but it resets EVERYTHING back to the moment when the worksheet was loaded into the application, what we lovingly call the "nuclear" option.
Hopefully one of the Tableau gurus will give us a elegant work-around to this issue...
I've also come across this. The only solution I found was to add the hierarchy a second time, which is better than nothing.
I am doing this on a bar chart, so unfortunately I show my hierarchy both as the bottom X axis and again at the top. I've attached the result.
I too would love to hear about a real solution to this vanishing drilldown button problem.
