Thank you for your report!
However, this issue is Working as Intended.
The report you have submitted is working as intended: heavy core is supposed to drop itself when mined with any tool.
Please note, that mechanics of the game may change between updates.
Things such as graphics, sounds, world creation, biomes, redstone, villagers, and animals may not work the same in current versions.

Can confirm, relates to MCPE-180441.
This could be intended, the 1.21.0.20 changelog only states that pickaxe is the preferred tool of heavy core.
