CC2023- New Premiere export panel settings not sending properly to Media Encoder

Been having issues with the new Premiere export panel since it was introduced:

1) when I want to overwrite a previous file with the same name, Premiere gives me the "this will overwrite..." window.  Click okay.  Send to Media Encoder.  It'll still export with a "_1" at the end.

2) My video has a captions track.  Captions are turned off in the Premiere export panel.  Send to Media Encoder.  It exports with captions burned in.  Or conversely, I turn on Burn In Captions in the Premiere Export panel, send to Media Encoder, Captions panel is greyed out and there's no option to turn them on at all.

I'd resort to exporting direcly from Premiere but since there's no preview window, you never know what you're gonna get until the file finishes rendering.  Might have offline footage since Premiere and AE linked media don't always seem to talk to each other and need a restart (another bug), might have captions burned in when you turned them off, might have a ton of black at the tail since it doesn't just default to Render Sequence In/Out, etc. (burns me all the time too).
