Converting Scene Components to Blueprints has incorrect result

Been having troubles with this feature but not sure what I might be doing wrong. Any ideas?

Step 1:
Select 4 walls and a floor in my scene.

Step 2:
Convert scene components to Blueprint Class

This abomination

Expected Result:
Something much much closer to image one that I can then place multiple times in my level with ease.

So I found a solution. If you make sure the other parts aren’t children of each other it appears to work correctly. Not sure if this is intended.
