Adding of Thumbnail does not Add until Re-Editing

[Astriker]

When adding a thumbnail to a post, clicking the image from the gallery, click thumbnail. The "Done" appears, I click Save All Changes, and Save again. Click the X to exit the media page, click Publish and the thumbnail does not appear. The post is still open, I go through the same steps above, and then the Thumbnail does appear. The thumbnail should be accepted in the first post / publishing of a blog entry.
