I couldn't find that in the output as well, not sure why.
when I run it manually, I am declaring the variables first and running the sed command as it is done by the script, with the variables. I only used the "echo" commands to show their contents.
Running it with the variable contents also works fine, by the way.
Please find below the full output.
