Issue Details

I cannot add my global variable to a project library. There are multiple instances of the global variable in my code and some of them are grayed out. If the grayed out instances are replaced with the with a new instance of the global variable, they default to the last value in the global variable. My LabVIEW project shows a lot of missing or incorrect dependencies as well.


Manually resolve the project dependency conflicts and then the grayed out global variable instances will be accessible again. Once the dependencies are resolved, you should be able to add the global variable to a project library as well.
