weird lava glitch (remake)

Weird Accor's when a large lava space is covered with block a the lava glitches out and when ever you replace the lava and break the block replacing the lava, the lava comes back and the flow is even more strange. the lava only flows in one way (Sorry Mojang that I made this Incomplete its because the .mp4 files were "too big" so I Couldn't Get Proof, I am Sorry)
