I've got an on hold project (appears in sidebar when I am showing On Hold projects). If I go to the inbox, create a new action, tab to the project field and start typing the name of the on hold project, it shows up in the list that appears. Now, if I do the same with a dropped project, or a project that is contained in a dropped folder, it does not appear in the list. I suspect this is what is happening in your case.
