The issue is on our builds we have no issues with our in house A310 and other aircraft. CRJ is the only one causing issues.
We will take another further look into this, but for now advise you to follow the following steps:
Start MSFS
For those with Premium Edition, search for the Asobo EGLL in the content manager and delete
Enable rolling cache (if not already enabled), delete it and turn it off
Exit MSFS
Remove everything from your community folder (cut and paste to a different location)
Delete the content.xml
Start MSFS
Exit MSFS
Install just the Inibuilds EGLL in to the community folder (and move to your MSFS Addons Linker Folder and enable if using), and the FBW aircraft if desired
Start MSFS and see if it is still the same and report back (enable rolling cache is desired).
