Executing error while executing sed command

Below given sed command is working fine on online BASH & KSH shell, but getting an error "Illegal operation --r" while trying to run it on linux server.

I'm trying to make a regex to parse "MFBBMYKLAXXX" from first line.

echo "{1:F01MFBBMYKLAXXX2474811384}{2:O3001434181108BKKBTHBKBXXX12203020241811081534N}{3:{108:241C182AFFD4403C}}{4: :15A:

Thanks in advance :)
