SIMPLE DIY ENVELOPE GENERATOR confusion

So I build the simple-envelope-generator with AD/AR switch, but I’m a bit confused as to what the trig setting should be doing. In gate mode the circuit behaves like I would expect, but in trig mode, it only works when I set the attack to zero. Is this be design and I don’t understand the functionality, or do I have to look for an error in my build?

Any help appreciated :slight_smile:
