How works the tags on dlive?

Today i uploaded my first video to dlive.

Before the publish, its need to add a main Category, and a Subcategory.
And sometimes, when i watch a dlive video, i see, how use the other users their tags.
Ok, its simple, so i used four other relevant tags.
And when i check that on steemit, i saw, the first three tag its not my tags. And in Explore, i cant see that video on the list below the right tag.

So, how its work? I made a mistake? Or miss something?
