[Help] Tried editing a mod now mod will not show up.

[Number1Bubbie]

As the title explains, I tried to edit the mod "Strange New Worlds" so that you can not colonize asteroids. I do not know if I manage to make it work since now the mod does not show up in the mods window of the launcher. In the files of the mod all I did was remove anything with asteroid that was different from the vanilla planet class file .Also I am on a mac, and it would be nice if for a solution you do not say "Get a PC". And thank you to all who help.
I hope the screenshots will be of use.

Similar thing happened to me once when I tried to change a mod from Steam workshop.
It worked to unzip the mod, move it to the myocuments/.../mods folder, make the change and create a new mod file.
