To get the same fun fact position, I must enter the opposite values shown in Pasan's video.

Following the video about auto-layout, I've done the same the steps on my xcode to see what happens. If I don't change anything, the fun fact gets displayed under the button and not slightly above as shown in the course video. I've noted that when I press "Ctrl" and drag to click on "Center vertically in the container", it creates a third label in constraints on the right menu but no values are set. When Pasan does it, a value of 73,5 is set automatically, pushing the fun fact just a little bit above the button. To get the same result on the scheme, I must enter a negative value to display upwards the fun fact. The most interesting fact is if I enter "-73,5" as constant when I edit the "Align center Y to: Superview" constraint, I get the exact same display shown in Pasan's video! All my constraints are trailed or aligned to superview and I have also have one warning saying that "Frame for "FunFactLabel" will be different at run time". Does anyone can explain me what's happening underneath the hood? It's very frustrating to see no questions related to this course are being answered so far...Thanks for your help!
