Wrong error in dependencies

I have made an add-on that contains a behavior pack and a resource pack. In the behavior pack manifest I have typed the tag "dependencies" so that it depends on the resource pack. I have written the correct UUID in the "dependencies" tag, but when I am in the settings and click "Storage" it says that this dependency is missing. However, when I create a new world and put the behavior pack, the resource pack is automatically selected too, as usually.
