Your second example works fine for me in the desktop version of Logos 8 and on an iPhone. I wonder if it might be a problem with resource prioritisaton for you? What is the resource shown in the popup in your screenshot?
The resources started working yesterday in the Summa. Maybe something got fixed on my tablet?
