[BUG] App not detecting album art

[mr0no]

Version: 1.0.4.0126
Device: Nexus 4

I downloaded album art using an app that does it automatically (album art file isn't actually copied to the album folder), and MediaMonkey cannot detect it. I tried using clear data and clear cache options in app setting but it didn't help.
Album art shows like expected in Google's Play music app (after clearing data), and Songbird (without needing to clear the data).

I tried updating my media library using an app. Also didn't help
