Switch Possible volcano ancient doll glitch?

[lolabug67]

I'm on switch version 1.6.9 build 37, and when I dropped an ancient doll in the volcano caldera lava, nothing happened. I took off my magnet ring, opened my inventory, threw the doll out, it sat there for a second then fell in with a splash but I did not get the far away stone. Did I do it wrong or is this a glitch? I've had other glitches as well across the game.

You have to throw the item in like how you would throw a fish into a fish pond, hover your cursor or face the water and click

it's different than throwing it out of the inventory like how you did
