Check which update site of the Extension Library you installed. There is a specific update site that includes Domino Designer tooling called updateSiteOpenNTF-designer.zip. It sounds like you may have just installed the updateSiteOpenNTF.zip update site.
I've not tried, but installing from the -designer update site may install just the additional plugins required. This will avoid you needing to uninstall the Extension Library.
