Waves VST3 plugin issues

Hi all,

I've just started to use two Waves VST3 plugins in my Premiere Pro workflow. However there are 2 issues that have come up:

1) Premiere Pro's auto voice transcription engine doesn't work if any Waves plugins have been applied - I get the "RawPCM (Exporter:17)" error.  The workaround is to transcribe and caption prior to applying the Waves plugins.

2) My usual workflow is to send the completed Premiere Pro file to Media Encoder, where I have some user-genenerated presets that optimize the video at various framerates, crops, and with/without capctions. Sending the above Premiere Pro file to Media Encoder and selecting an output preset that ignores captions doesn't work. In other words, Media Encoder is rendering the Premiere Pro captions regards of whatever I  in Media Encoder. The only workaround here is to manually turn off the Premiere Pro caption track in the sequence timeline.

Note that sending a Premiere Pro sequence (no Waves plugins) with captions, to Media Encoder set to output captions, works great.

I've tried using a different machine and OS, but I get the same result.

I've approached Waves for help. They say boths issues are Adobe issues because they can repeat the problem using other VST3 plugins, such as ones from FabFilter. Waves advise I raise the issue with Adobe. So here I am. 

The tech details:
MacBook Pro 64GB of memory, OS X 12.6.1, Premiere 23 and (now) 23.1
Mac Studio  64GB of memory, OS X 13.0.1, Premiere 22

I've got a couple of screenshot videos I've made to document the issue. While I'm not comfortable posting them to a public forum, I'm happy to send them to anyone upon request.
