0.78 color labels on folders disappear with no cache

[shadowpower]

In 0.78 64b windows 8.1 64b if I disable thumbnail caching the color labels on the folders disappear when you assign, leave the folder and enter again (sometimes you need to do it multiple times). If I delete thumb.db I can still see the color labels on folders, until I view them once in the browser and leave that folder, when you come to the folder again color labels are gone (for folders only, images are untouched).
