I have my lootfilter set up so that everything that is not explicitly shown, gets hidden.
So, naturally, I want to / need to add woven echos to my filter.
but when I click here 
nothing happens afterwards:
That surely can’t be right.
Soooo, what do I need to do so that my echoes are not getting hidden?
(The log file does not write an entry for that, btw.)
