Tween angle not repeating

I’ve never used tweens before and I thought I would give it a go, but I’m having trouble with tweening the angle of an object.

As you can see above, the first time I press z, the angle tween works (along with the movement one). Subsequent presses, however, do not activate the angle tween. The movement tween still works though, which just confuses me more.

What am I missing?
