Double clicking (to reset) doesn't work on delay and reverb level knobs

Double clicking (to reset) doesn't work on delay and reverb level knobs (has no effect).
(IMO it should put the value to 0 when double clicked.)

Here it is working. Give me more details... What OS are you using? The double click works for the rest of the controls?

Yes, it works for the rest of the controls.
