Steps to reproduce:
1. Create new ContentType i.e. "News".
2. Add a single Textline field i.e. "Title".
3. Set Default field for sorting children for Location priority with Ascending param.
4. Create new News content anywhere.
5. Add the second location for newly created News content.
6. Observe Sub-items sorting order in the Details tab for this content.

Expected result:
Sub-items sorting order for a new location should have the same value as one that has been set in ContentType.

Actual result:
Sub-items sorting order for a new location is not the same as one that has been set in this ContentType.
