"Configure as Synth" for VST3 is different? Stutter Edit

iZotope Stutter Edit loads by default as a VST audio effect.
 
I click on the properties in the plug-in manager and select it to be configured as a synth.
 
On the next re-scan, the VST2 version appears as a VST instrument.
But the VST3 version stays on the Audio menu in the browser.
If I load the VST3 and check it's properties, it is still marked as a synth and it works fine.
 
In the plug-in manager, the reverse happens - Stutter Edit stays in the VST2 audio folder, but for VST3 it moves to the instrument folder. This is rather bizarre.
 
So this is really not much of a problem, since it works properly, but shouldn't VST2 and 3 work the same way as far as plug-in menu behavior goes?
 
iZotope VocalSynth behaves the same way - works properly as a synth, but the menu display is wonky.

As an aside, is there any particular reason why you're configuring Stutter Edit as a synth? I use it as an effect and it works great like that....

To get MIDI input. This was the older way to do it. Now that we have the MIDI menu on the VST header I guess this isn't necessary.
