BUG: Firmware V5.08.115 Incorrectly Advising USB Format Not Supported

I have an external USB formatted as exFAT which is a supported format on OS5 per WD’s instruction manual, however ever since my NAS updated to latest firmware V5.08.115 it’s now showing an error in the Web Dashboard that the USB is not a supported format, despite the USB accessible via the NAS.

@joshobrien just sent you a PM for more detailed information, and then saw this post.
Can you check your PM and sent that information to support and let me know the case number?
