Philco 42-1012 Power up
#26

I would suspect the pushbuttons have an individual tuned circuit for each frequency selected. Since they only have to tune a small range the Q it higher than the main dial circuit. This will make it tune in a bit better and have a sharper peak when aligning it.
As for the SW issue if you have a cap meter you could check the micas to see if they are within spec.
