Dude. The plugin is coming from the author of Spigot (the one who made the plugin you used). Aternos won't in charge of adding it. Ask the plugin's author
What plugin are you talking about? Do you have a link to it?
Did you already check the console for errors?

By what he mean like he want to add the Cosmetic one (but that feature does not exist with the plugin)
P.S: Shortcut: He wants the plugin author to add it 
btw don't spam posts over and over
Oh beside, do you change any configs in that plugin?. On the other way, in the video you sent above, you just only move straight, and not up
Nah. You cannot blame Aternos team just for that plugin. They added the plugins from the Bukkit/Spigot source, so the plugin you have is made from the plugin author, not them.
How about let me see if that works for me
Uh.. so you blame Aternos now? 
- Plugin Problems are not Aternos Problems. Also officially we don't support plugin problems, as these are topics of the plugins and not of Aternos.
- As thienbao already said, our system downloads the plugins directly from spigot or bukkit, so an "upload error" can't be the cause.
To help you with your problem:
I still don't really understand what your problem is.
- Please give me a link to the plugin from spigotmc/dev.bukkit or from our plugin list.
- What should be the normal behaviour and what happens in your case?
- Did you already check the log? Maybe there is and error message. You can also share the log with us using the share button on https://aternos.org/log
- Could the problem be caused by an misconfiguration of the plugin? Then share the config with us.
