Multiple Initialization Error with Projucer Update

Hi, I’m new to JUCE and c++, so go easy on me.
I started my project with an old version of the Projucer and have updated to a new version of JUCE since.
I am receiving a few repetitive build errors when compiling my project in Visual Studio stating: redefinition; multiple initialization. These error messages direct me to the auto-generated JuceHeader.h file, which has comments explaining that my modules are out of date, and I need to re-save my project with the latest version of the Projucer. I have done this (or believe I have done this) multiple times, but the error persists. Any thoughts?
