I notice recently that when I try to insert an audio effect in the FX bin from the recently used list nothing happens.
Inserting the effect in the normal way is fine. The recently used list seems to have the correct content (the 5 most recent effects that I have used).
I am clicking on the + in the FX bin, then selecting "Insert Audio FX...", then selecting one of the listed effects in the Recently Used list at the top.
Is this a known bug or a setting somewhere that I have missed? It was definitely working before but I can't recall when it stopped working.
