Latest Premiere Pro update has ruined captions

Does anyone seem to know why on the latest version of PP, when auto transcribing video tracks, the captions it generates are laughably bad, missing out entire sentences, getting words completely wrong and just all in all meaning that you have to transcribe the video yourself. I never had issues with the previous versions but after updating it can't handle it. For context, the audio is clean and clear and testing on a seperate system which is still using the older version of PP it handled it like usual.
