Reflect does embed some info into Rescue Media to help achieve drive letter consistency between Windows and Rescue (with regular Windows PE, it's normal for your drive letters to be all over the place), but it doesn't always work, and being a BitLocker user myself, I've noticed the inconsistency quite a bit too. My guess as to why BitLocker affects things is that drive letters get assigned before partitions unlock, and the info Reflect embeds into Rescue Media to "match" known partitions to known drive letters isn't usable while partitions are still locked, so it's too late by the time they're unlocked. However, drive letters are arbitrary and only exist while a given instance of Windows or Windows PE/RE is running. When you switch back to "real" Windows, the partition that the system booted from will always be C, and Windows will still remember the drive letters that it (or you) last assigned to any other partitions. Worst case, if you make a significant change to your disks in Rescue, Windows might not recognize it anymore and therefore might assign a different drive letter than you expected, but you can fix that quickly in Disk Management. Just obviously make sure that when performing operations within Reflect (or Command Prompt in Rescue), you're targeting the partition you actually mean to be rather than thinking in terms of drive letters.
In terms of BitLocker on GPT Disk 3, BitLocker is a partition-level encryption solution, not a disk-level encryption solution. So if you want to encrypt the second partition, you can do so, but it's normal that you would have to enable that separately. And of course you'll need to back up a separate Recovery Key for it.
On a side note, the GPT GUIDs you obscured on GPT Disks 3 and 5 aren't sensitive info. Those are randomly generated whenever a disk is initialized with a GPT partition layout, just like the much shorter hex strings next to the MBR disk listings that you left in the clear. And I believe the other portion was the serial number of the hard drive? That's not particularly sensitive either. Not that they're necessary to see for these purposes of course, but there's no need to take time obscuring them either.
