Looks to me that everything is in the right place with respect to it’s location in the StackView. I suspect it’s a constraint issue as you originally alluded to.
These are all my constraints expanded so you can see them. Maybe check them against yours to see if there is anything missing.
That second error is a mystery to me. Sorry, I’m no help there.
(edit) I just searched online and found a thread on StackOverflow (this is a great resource but you have to be careful to not be misled).
The thread said: The warning is unimportant. If you really object to it, run the app on a device instead of in a simulator. The console message will go away.
