   • Create counters for the following:
     • User Subscriptions
     • Votes by User
     • User's Blog Entry Updates
     • User's Blog Entries
     • User's Comments
3. Save
4. Click back into the configuration

Expected result:
Counter settings will remain as selected.

Actual result:
Counters all revert back to the default "Cancelled Subscriptions to User's Assets" even after Save confirmation in the first part (see gif)
