Groups output routing lose and loss of custom settings

Hi guys! have a 2 questions

  1. I using N 11.0.41 and observe strange prob - every time if closed any progect and reopen - output routing selectively (only on several 5.1 groups) was deleted. Every time.

2 .Also. If crashed N11 (but not everysing) im losing personal preference and all media bay settings, but DOP favourits presets remain as before. This happens both on all versions of the N11 and N10. Using a clean install Win10
