Poweramp not displaying song info

[Deadly_Poison630]

I honestly didn't know where else to ask this but here goes. So recently I added on my music onto my Galaxy S3. However some songs are missing info in the tags in Poweramp (Album name, artist name, track #, you get where i'm going). Yet when I look up the same songs in the stock music player, all the missing info is there. Anybody know what caused this, and/or how I can fix this?
