Open Stack

Hi,
I’ve created a new flavor in my openstack cloud, called xsmall. When I started a new instance with that flavor, I found that it is connected to a non-existing flavor ID, which is resolved to my xsmall new flavor:

as you can see "nova show” shows an ID for xsmall which is different than that one of the output of flavor-list or flavor-show.
While it seems not to be a problem for the end-user who uses the command-line, it becomes a 'semi-serious' problem for 3rd party clients using the nova APIs (v2).

Is this a known issue or am I doing something wrong ?
