Am I missing a library or something ?

Indeed. You're missing libraries which aren't included in the nolib version. Unless you understand what libraries are and how they function, use the default download option from CurseForge.

If you're using the CurseForge app to download and manage your addons, make sure that the "Install Libraries Separately" option is unchecked (right-click AdiBags):

Also, verify that the "Library Preference" option is toggled off in the game specific settings for World of Warcraft:

If both options are configured correctly and it's still installing the nolib version, submit a support ticket here.
