Load Custom Mesh Missing

Hi, when I try to load a 3d mesh (full character FYI). it shows me the load custom mesh section without a dropdown.

However, whenever I watch a youtube tutorial about how to convert a 3d mesh into metahuman, it shows a drop down available there:

I have downloaded metahuman core data and all metahuman plugins to my project. What am I missing here?
