Content specified in the class library is not migrated during ClickOnce deployment

I have a WinForms solution, C #, which uses a ClickOnce deployment that causes some problems with resource files. In short, files marked as content in a class library project are not copied to the output tray / folder after deployment using ClickOnce.

Here is the basic structure of the solution (it contains a lot more projects than the ones I list below)

Solution 
 |--Gui 1 Project
 |  |--References
 |  |  |--ClassLibrary
 |--Gui 2 Project
 |  |--References
 |  |  |--ClassLibrary
 |--Main Gui Project  (StartUp Project)
 |  |--References
 |  |  |--Gui 1 Project
 |  |  |--Gui 2 Project
 |  |  |--ClassLibrary
 |  |--Datafile.wav    (Build Action: Content, Copy-if-newer)
 |  |--Mods.xml        (Build Action: Content, Copy-if-newer)
 |  |--VariousSourceFiles.cs
 |--ClassLibrary
 |  |--Resources
 |  |  |--Elements.xml     (Build Action: Content, Copy-if-newer)
 |  |  |--AminoAcids.xml   (Build Action: Content, Copy-if-newer)
 |  |--VariousSourceFiles.cs
