Proxy appending _Proxymov Suffix instead of _Proxy
I'm running Windows Premiere Pro (Beta) V24.5.0 BETA (Build 6)
The Project Ingest settings are set to:

All the video files within the project have had Proxy files generated for them such that C0574 which is an MP4 video file would have C0574_Proxy.mov as the proxy file.
Now the Proxy files are not being recognised at all. I imported a new video file and it generated a proxy named C0573_Proxymov.mov
I manually deleted all the existing proxy files and reran "Create Proxies" across all the video files in the project.
Every one was created with a suffix of _Proxymov and none of them are recognised in Premiere.
I then closed the project; manually renamed all the Proxy Files and reopened the project again.
They are still not being recognised.
This issue has just started today.
Not sure what to try next and any suggestions would be welcome.
