Custom resource pack does not load, reason being “Duplicate Pack Detected”

This is my first time posting here, so any suggestions would be welcome.

When importing my custom texture pack, it fails to show up under the reason “Duplicate pack detected”. The resource pack in question (first screenshot) has my real name on it, which I do not wish to reveal. Another custom resource pack (screenshot 3) I ported shows up, but doesn’t change even a single texture. Please fix it ASAP!
