Details panel showing incorrect object rotation?

Ok, I could be wrong but I think that unreal engine isnt showing the correct rotation of an object in my scene. I am very new to the engine though so please let me know how I’m wrong.

In the image above you can see an object that I have rotated by 90 degrees about the z-axis. In the details panel you can indeed see that the object rotation is (0,0,90). Also the important thing to note here is that the x,y and z axis of the object do not align with the x,y and z axis of the world (Compare the axis of the object with the world axis shown in the bottom left corner)

Now In this above image I have simply rotated the object along its local x-axis or in other words I have rotated the object along the worlds y-axis. Therefore, In our current state the objects local rotation is (40,0,90) and its world rotation is (0,40,90)

In the above image I have navigated to the details panel and under the Transform section, I have opened the dropdown revealing two rotation types. “Relative” rotation which I assume is basically local rotation and “World” rotation which is quite self explanatory. Now currently I am being shown the local rotation of the object which indeed seems to be correct. However, when I click on the “World” option…

Nothing changes…The values stay the same. Shouldnt the values be updated to (0,40,90) since that is the objects world rotation??

I think the relative and the world are the same, because the ball isn’t actually relative to anything yet, except the world.

If you attached it to something, things might be different.
