Creating issues in JIRA sets ranking inconsistently.

Steps to Replicate the Problem:

• Creating an Issue from a view other than the Planning Board (e.g. from the dashboard) causes the issue to appear at the bottom of the Planning View.
• When creating it from the Planning View, the new ticket will automatically appear underneath whichever ticket is currently selected.
• If no ticket is selected in the Planning View and a new ticket is added, that ticket will appear at the TOP of the backlog. To reproduce, just manually remove the selectedIssue=XXX query string parameter from the Planning View URL and try to create a new ticket.

Expected Behavior:

Creating a new issue should put it to the bottom of the backlog at all times, to prevent accidentally giving the issue a priority.
