Geckolib "Create animated entity" Not showing Up

so, i recently downloaded mcreator, and i wanted to make a mod with it, and my friend recommended i use the geckolib plugin for my mod so i can use animated entities and such, but when i go to create a new "animated entity" nothing shows up, infact, all of the geckolib plugin features dont show up besides "Import Geckolib Model", "Import Display Settings", "Entity Element Converter" and "Geckolib Element Converter"

i have "Java Plugins" Enabled, and i also have Geckolib Plugin enabled in the External API's Tab
