Thanks to both of you for your suggestions. I will try them today.
I certainly don't expect that it would be a problem with Quartus, but it seems so strange. I worked with Quartus quite a bit about a year ago and never had any problems like this.
It is a new board. All the pins are assigned correctly.
Again thank you.

Hi John,
is it possible that the board itself is the problem ?
An easy way to check what Quartus did with your design is to look into the RTL or Technology View.
Kind regards
