Water with lava touches but does not create cobble

DEVELOPERS PLEASE ATTENTION!!!!!!!!!!!!!!!Developers please fix this bug !!!!!!!

This error begins with snapshots 1.14 and so was not fixed in the pre-releases of Minecraft 1.14.1. As you can see in the screenshot, it shows that the lava touches water but does not create a cobblestone.I created a partition 4 in length and 1 block wide and retreated two blocks where the lava with water would flow out poured lava into one partition from the blocks and into another water such a bug!
