Hi

I have seen that this happens.

Try and go to prepare tab, align beams/change beam orientation tool, and select all beams that need to be aligned and there is an option to use a surface to align to - use one of your surfaces that suits best.

Or select all the beams, and use to rotate/orientation tool to rotate them 180 degrees or as needed.
That is the only thing I can suggest - thank you.
