Problem with handrails bend members 360deg donuts 08.11.11.207

Hello

We have big problems when we move on new version of PS 08.11.11.207 from 08.11.11.87.

The laptops and system is brand new. Win 10 and autocad 2017 with SP1. Also AecModeler.dbx file was changed. If we open the model in new system all pipe elbows it looks like donuts.

If we create on this model any new they looks the same. I remeber that in Autocad 2015 was the same problem but service pack from autodesk resolved that.

Do you have idea what we can do right now?? I have very big constructions and much more handrails. Please, help us.

Also export to psb and import again doesn't work.
