How to creat a tree with kindom, phylum, class, order, family,genus name?

I want to have a tree with kindom, phylum, class, order, family,genus name. However, in the generated picture only cellular organism and not assigned were found. How to show kindom, phylum, class, order, family,genus name ?

have you tried the “uncollapse all” option under the ‘tree’ toolbar?

Thank you, OmarKR! I have tried it, you are right.
