What do you mean by "showing me the old values"? The signal names, or is it that when you look at the waves it seems that it is still the old logic that is in place?

If it is just the signal names, the ones that are not part of your design any more are shown in red, and you need manually to delete them and insert the new signals in the window.

If it is just the wave that looks the same, did you click again on "run analysis"? If you still see what looks like the old logic would generate, then it means that either your modified code wasn't used by quartus, or that it doesn't do what you think it did. In either case check with the RTL viewer what Quartus synthesized.
