Autopsy BitLocker

I am trying to create a full forensic SSD image in FTK Imager (Free Version) by using the BitLocker Recovery Key then creating the BitLocker Unlocked image in FTK Imager then ingesting it into Autopsy but every attempt has failed with a warning of BitLocker Encrypted Volume Detected in Autopsy and it being clear that no data was analyzed even though I verified that the image was decrypted with the correct recovery key.

When checking settings on the Windows server that I am using for Forensics I found that BitLocker Components are not enabled. Is this causing the issue or is the fact that I made the image with the FTK Imager Default Image Fragment Size left at 1500MB?

Would another tool like Magnet Acquire work better?
