So this is a minor issue which is goin on a while ago in MDT, I know Noggie fixed a bit once, but looks like it's still happening here and there.

So it's 4th week, you can see the week number is green, but the angry triangle is still there, warning you it's a wrong week. You can recreate this issue by choosing any route which has stored a different week - getting the triangle correctly - then changing dungeon, which having already set a correct route with a correct week - but the triangle is still out.
