Did you found a solution? I have a similar problem:
I selected a value for my AppEntity "category", then want to execute the shortcut and run into the loop. I diagnosed, that the parameter of my intent is still nil and stays so after selecting a value in the dialog.
Also, I have a second parameter "categoryEntry", which depends on the selection of the "category" value. But this also fails, because of the internal nil value of the category :/
