Where does Infuse source the album art? I can get totally different cover art (right movie) when rebuilding my library

So this is pretty strange…

Sometimes when I need to rebuild my library and redownload the album art and meta data, it sometimes would download completely different album cover art than previous.

For example for the movie La La Land, today it downloaded some strange La La Land album cover that I’ve never seen before.

Just to be clear, the correct movie is downloaded but just some weird different cover I’ve never seen before.

If the parameters are the same as last time, how come the album cover is different?
