the categories with only voice channels are gone.

the categories with only voice channels are gone. with all the channels as if someone had hidden them. when you create a new category and add only the voice channel to it the next time, it disappears. if you add the text channel first and then the voice channels, it will remain, but if you delete the text channel, then the remaining voice channels along with the category will disappear. All the categories are visible on the phone and my friends have them too ,as well as through the site are visible. I want to say that I am the creator of the server, as well as on some other servers there are no categories
