Advanced Sessions Plugin

Currently running UE 4.27.1, installed plugins through a source build of the engine, I noticed it says above “DO NOT install through the source plugins folder but your project plugins folder”. I installed both of the modules and rebuilt the editor, when I opened the game project editor I get greeted with a message saying “The following modules are missing or built with a different engine version:” it lists my game name, and the two modules “AdvancedSessions, and AdvancedSteamSessions” it asked if I would like to rebuild the project. After rebuilding the project it says “Engine modules are out of date, and cannot be compiled while the engine is running. Please build through your IDE.” What does this mean and how do I get the plugins to work? thank you much appreciaited.
