Ancient Debris burn into fire and lava.

I was in my survival world, searching for the new item, the Ancient Debris. And of course, I found some. Although, when I broke one, it dropped directly into lava, it got catched on fire, and it just disappeared. I tried to see if it does the same thing on creative, and it came out as a "yes". I'd appreciate extremely much if this will be fixed. Thank you, and have a great day there.
