I just tested it out with a new project in MZ, and with a fresh download the plugin from this page, and it's working for me. MZ says that my current corescript is 1.9.0 which appears to be the latest update that I have access to. If you have scripting conflicts it might be another plugin causing problems.
For reference, here's a screenshot of the character sheet imported into RPGMaker with the name that I gave it, which works with the alignment plugin as expected: movement and collision test.

Welp, from your screenshot and feedback and some futzing around I think found the issue, in case you want to add it as a note to the guide/plugin:
It does not work if the file is inside a subfolder (for example img/characters/actors) rather than just img/characters.
In any case with that fixed I can advance, cheers and thanks for the cool assets o/
