World Bundle Packs NOT WORKING

I have been trying to put a resource pack in my world for ages now, and It doesn't work. I have the resource pack, and it works if I use it as a normal Resource pack BUT if I put it in my world file and rename it to "resources.zip", IT DOESN'T WORK! I have other worlds by other people that have bundled resource packs and they work but when I try to make my own, it doesn't work. I think is because I'm on a MAC, but IDK. I try rename it "resources.zip" and I try Compressing the folder "resources" so it becomes a ZIP file and is named "resources.zip" but nothing works. I tried playing around with other Bundled worlds and I found out that it works when you load it the first time, but if you UNZIP the file and REZIP it, it doesn't work anymore. I don't know why, but it doesn't work.

Picture 1 is of the Game Output (Don't mind the "14 Blocks filled" and stuff, that's just the map)

Picture 2 is ingame, if the resource pack worked it SHOULD make the Moon Invisible.
