Sniffer Texture & Sniffer Generator Texture appear invisible.

Recently, when I was trying to get the new Sniffer achievement and upgraded, the Sniffer mob texture and Sniffer spawner appeared invisible. I thought it was a world bug, but when I created another world, I realized it was a game bug. I disabled all textures in the game but it still shows up like this. I have the proof I need your help, please, thank you.
