I'm trying to add new contact to empty list in Sitecore List Manager. I click "Create and add new contact", type appropriate data and click "Save" button. After that I get following messages:
Please note that this list is currently being built and is locked.
and
Please note that contacts in the list are currently being indexed, so not all contacts are available to view at this time. 0 out of 1 contacts are currently indexed.
Then I use "Index manager" and rebuild "Sitecore_list_index". After that, I go back to List Manager and unlock list manually.
Finally, I can't see any contacts in the list. Can't figure out what's wrong.
EDITED
Sitecore version is 8.1 (it was upgraded from 8.0)
