Description of problem:
When installing f13 Alpha live iso I found that if you edit a newly created LVM where encryption was selected it 'forgets' about it when you click on ok. 

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Create a new LVM group, select encrypted, click ok.
2. Edit the new LVM group, click ok.
3. Notice that the lock for that LVM is now gone.
4. Edit the new LVM group, notice that encrypted is no longer selected.
  
Actual results:
encryption not selected
