Hi,
Yes, we couldn't fix it before releasing the final version. We are hoping to finish it for the next update though (build 50xx) - You will find it in the release note as fix #252335 when it is done.
In the meantime, this happens in Floor Plan and 3D view, however it works fine on S/E/IE views and also from the Settings dialog, or (as you mentioned) you can just turn them invisible. You can keep working with that in mind until the fix is ready.
