Outgoing CID dial pattern includes objects that causes trunk to reject call due to incorrect number

FreePBX version 14.0.5.2

Outgoing calls being rejected by trunk due to invalid number format. 

Free PBX is outputting additional characters into the dial output string which is causing this error. It has been verified that the trunk is receiving these characters.

Example output (extraneous characters in red) : 

Executing [s@macro-dialout-trunk:32] Dial("SIP/100-00000049", "SIP/digium-siptrunk/*dialed number*@TLC_*outgoing CID*,300,Tb(func-apply-sipheaders^s^1)") in new stack

Upon checking all CID fields, no fields contain "TLC_" and are set to the correct CID.

All previous lines in CLI (running in level 5) show correct CID setting being applied.

It is possible that this erroneous value was entered and applied to an earlier configuration, but it is no longer present in the GUI and multiple configurations and settings have been tried/reapplied since.
