You have some typos there in the screen shots... "reclentley" (recently), and "flie" (file).

It would also be good if you changed the name of the mod as there already is an Estuary Plus mod here https://forum.kodi.tv/showthread.php?tid=307916 having 2 named the same could be potentially confusing.

[Edit] I see you've now changed thread title, thank you for that.
