In this setup the sticky piston should extend and retrack on a button press. But if i hold my mousebutton and spam button presses, one piston phase is skipped and the redstoneblock keep extended

Buttonspamming with observerblocks

This isn't a bug. This is perfectly normal. When the button is pressed, it updates the block under it. That update is then picked up by the observer and it puts an output of one tick. The output then powers the piston, causing it to extend. Here's the thing though: When a sticky piston receives a one-tick pulse, they only push out the block. They don't bring it back in. This is what you are seeing.
What you have there is a very simple T flip flop. You can use the block as an output, and every time you hit the button, it switches from on to off (Like a lever, but with a button instead)
I hope all that makes sense
