I don’t really know if this is a bug but it is pretty buggy. If I rotate a part 90° About the x- axis, the y and the z slider controls the same axis. I don’t know if anyone else is having this problem but I do think this should be addressed. I can’t tilt my part sideways because there is no slider that would rotate my part in the direction I want it to go. I am now forced to use the rise and run instead of rotation.

It's called gimbal lock, apparently. Two axis match up. Multi-select the part or reset rotation as CrashFighter suggested.
just reset the rotation, that should fix it.
