OBD U8 legacy structural steel elements get scaled x100 when modifying.

I recently upgraded my OBD to version 10.08.00.44 and now I am unable to modify my old model created in U7. Every time I try to extend a steel beam or a column it appears 100 times bigger. I can copy or move them around without any problems. When placing a new element from Legacy - Structural Elements menu they also appear 100 times bigger. I tried to upgrade all legacy elements to ProStructures with Upgrade Structural Elements tool but the same problem occurs. Am I missing something obvious? Can't believe I am the only one with this problem, been searching this forum for the last hour but could find a similar thread.
