Project level variables are very unreliable for me. I am not sure what I might have done to cause my state, but a number of tests I just put together were all using a token variable I created at the project level. I needed to close Test Studio Api and return. When I returned and loaded the project, none of the tests are recognizing the project level variable no matter what I shift and change. (this was just minutes apart, the token is still valid as when I put it in the test directly with no variable - it works)
