Steps to reproduce:

1. Add sites A, B and C
2. Edit Site Settings of site A
3. In Parent Site, select site B. Then select site C. (WRONG: this situation should never be displayed. See attachment)
4. Save. Only one of the selected sites is saved as parent. (OK)

This also happens with parent organizations.
