Voukoder Pro breaks the "Export to YouTube" Destination UI

Well, here's another fun one. When the "YouTube" destination of the Export tab is set to use a Voukoder Pro preset, the UI in the Export panel gets all screwy, as seen in the attachment. I just toggled between two presets, and you can see what happens. Very odd. Trying to use the "Send to Media Encoder" or "Export" buttons doesn't do anything. Everything renders out perfectly fine in the "Media File" destination, but one of the reasons I pay for Premiere is for huge Media Encoder queues.

I'm not sure what kind of diagnostics you'd like? I'm not getting any errors, because it's not even making it to the moving parts, as far as I can tell. I've attached the scene (with an extra .txt extension), which is pretty simple, and the encoder profile in Premiere is basically the same.

[ed: one of these days I'm going to create a thread that's not about bugs & problems...]

Oh. That's...pretty rough, as it's essential to my workflow. Is this a thing that can be modified?

Mmm, probably, but I'd really like to stay in my workflow. I may go back to the "old" software, but don't worry, I'm not going to ask for a refund or anything Gotta pay the rent.
