>Also asked the Hospital, they said we cannot see your file linked to GC Key yet.
This is very odd. All they've to do is upload your data through eMedical. Did you upload your information sheet (provided by the hospital) with your PR application(I think you most likely did, else why would you get BIL)?
Regardless, if you got BIL, you are most likely MEP. If I were in your place, I'll call IRCC and confirm this. If they say there's an issue with your GCKey and eMedical - you'll get next steps to fix it - if they confirm everything is okay, you got nothing to worry about. It could also be that your panel physician didn't upload/forgot to upload your medicals (again, super rare and probably impossible given that you are R10 pass with BIL in place, BGS and Eligibility in progress or done).
To be very clear, what does your GCKey and PR tracker show? Can you post that below.
