I am marking as sunstone but probably core is related too...

How to reproduce in sunstone - attach volatile disk of type swap and fill Format field with for example 'ext3'
On the storage tab there is a line:

ID     Target     Image / Format-Size     Persistent     Save as     Actions     
0     vda     CentOS-7             NO         -         Snapshot  Detach
2     sda     2GB - ext3           NO         -         Detach

Here I added second swap disk with emty *Format' field and there is no clue that it is swap:

ID     Target     Image / Format-Size     Persistent     Save as     Actions     
0     vda     CentOS-7             NO         -         Snapshot  Detach
2     sda     2GB - ext3           NO         -         Detach
3     sdb     2GB                  NO         -         Detach

I would like swap disks Format to be always 'swap'.

And one little glitch - the header says Format-Size but data in the column is Size-Format.
