Chests in blacksmith buildings are empty

So i was seed hunting and found a seed with 4 blacksmiths in it , but when is opened their chests it was empty . Every single one of the 4 blacksmiths chests were empty. I thought it's was a seed issue . So i tried another seed but in that also blacksmiths chests were empty . I checked other villagers chests but they were normal it's an issue with blacksmiths only . If you are seeing this mojang please repaire it ..
