Loss in deadlift strength? What do? Help!

Long story short I’m doing the bridge 3.0 and I finshed week 8 about 2 weeks ago but been running it out. My squats feels amazing and bench they’re really going up about 5lbd every week. But my deadlifts are decreasing fast. 2 weeks ago I pulled 450 1@8 the last week only did 435 1@8 and today did only 405 1@8 what do? Do I pivot even though it’s only one lift decreasing or do I change my volume on my deadlifts please help thanks!

How long is left on the template? If your Deadlift has dropped 50lbs in 2 weeks and it really feels like it’s the same rpe then just take the low stress week now and pick back up where you left off after.
