For some reason the position of your blurry element is on a fractional pixel; while the inspector shows “174 px” it in fact lands at “174.5 px”. Hype tries to deal with integer values for position keyframes, so I’d be curious how it got in that state.
The workaround is to manually enter different value for the end keyframe for top/left positions and then enter back the previous value. This will clear it out. Also using “Position with CSS Left/Top” is a good workaround because CSS only accepts integral values anyways.
