There is a large difference between sourcing a file in the current shell
(. script.sh, where $0 remains unchanged) and executing a script
(./script, where $0 changes to the script name); and as you discovered,
there are a large number of scripts that are not usable when sourced
instead of run as a script.

At any rate, glad to hear that you got things sorted out.
