I copied one App into another (changing its name) and then moving it to another folder. When trying to link in (nested grid) the App is not showing on the list so making the link is impossible.
As you see on the screenshot (on the top) - the App is opened, then when I open the list it is missing. This is pretty serious !

OK I managed to fix this. I removed temporary files, removed -lib folder (from the project folder), changed theme to something else, then regenerated the whole project.
Now I the missing App is on the list as expected. It seems like many problems appear when I try to close Apps (copy Application1 to Application1_copy then rename it Application2). This seem also to apply to a missing ADD NEW RECORD button (which often is missing).
