I Cannot Find the Project I Want to Associate with the Program

I am on the Programs hub Projects tab and trying to associate a project with the program but the project is not listed.

You cannot associate a project with more than one program, therefore the Project Name drop-down only lists projects that are not already associated with a program. If you do not see the project you require, navigate to the Projects hub List view, locate the project, and look in the Program column to see if it is already associated with another program.

If you want to associate the project with a different program, you first have to disassociate it from the program to which it is currently associated.
