Length not shown in edit when adding a standalone recording

I wrote the recording length when creating edit http://musicbrainz.org/edit/14460120 , but it is shown as "?:??" on the edit page. The recording page shows the length correctly: http://musicbrainz.org/recording/e047adbf-8c7c-42a3-b24a-5d8a10ec5766 . Also happened today in http://musicbrainz.org/edit/14493214 .

Steps to reproduce:

• On an artist page, choose "add recording"
• Fill the recording name, track length and edit note, choose "enter edit"
• Look at the created edit
