Premiere Pro Transcribing into wrong language?

Hi. I 'm a video editor and I love editing my videos using the transcribe and edit feature in the latest premier pro. I have done this multiple times, but for some reason, today for this particular footage and audio file, Premier Pro keeps auto-transcribing them into different languages.

I have the settings in auto-detect language and auto-transcribe into English (UK). The video file and accompanying audio file of the same footage are in English, yet it's auto-transcribed the video file in Mandarin and then the audio file of the same footage in Taiwanese. 

It's me speaking in the video and I'm a native English speaker. I have quit the program, restarted the computer and started a new project and sequence, but every time I upload these files into Premier, it transcribes them into these languages.

I filmed another video on the same SD card on the same day and transcribed that file into English. Similarly, I recorded the audio using Audition, and I filmed and recorded several videos that day, and none of those files are having the issue.

Does anyone know how I can fix this? I have just finished editing another video from footage from the same SD card a couple of hours ago and didn't have this issue.
