Why the line moved

Why did the Cubs vs Mariners line move?

The spread did not move from its opening number (Mariners -1.5) even with 73% of the spread money on the Cubs. The total moved 1 point toward the under (8.5 to 7.5) even though 95% of the total money sits on the over; the under holds 5% of the money and 7% of the tickets, so the line moved away from the money side.
