Incorrect init value with CtkControl.env

[mkmarchan]

CtkControl.env appears to have the wrong initial value (2x the expected number). Here is a code snippet the reproduces the bug I'm seeing:

(
var synthDef;

synthDef = CtkSynthDef.new(\testSynthDef,
	{ arg freq = 440, gain = 0.0, dur = 1.0, outBus = 0;
		
		var trigger, sig, env, timer;
		
		env = EnvGen.ar(Env([0, 1, 1, 0], [0, dur, 0]), doneAction: 2);
		trigger = Impulse.ar(1.0);
		sig = SinOsc.ar(freq);
		
		SendTrig.ar(trigger, 0, freq);
		
		Out.ar(outBus, sig);
});

o = OSCFunc({ |msg|
	msg.postln;
}, "/tr", s.addr);

synthDef.note(starttime: 0.0, duration: 60)
.gain_(0.0)
.dur_(60)
.outBus_(0)
.freq_(CtkControl.env(Env([440, 440], [60], 'exp')))
.play;
)

The post window will show:
[ /tr, 1097, 0, 880.0 ]
[ /tr, 1097, 0, 440.0 ]
[ /tr, 1097, 0, 440.0 ]

Any insights into what's happening here? Has anyone run into this before?
