The reappearance of removed inner block after unlocking is a normal behavior in the editor, since the block has a locked layout (using templateLock="all"), thus having a fixed template structure. When you click “Unlock” in the editor UI, you’re unlocking the block-level lock, not the templateLock that manages the template structure. This behavior is also consistent with other blocks, such as stackable/blockquote.

As an alternative, we can simply clear the text content of the cents text instead of deleting the block.

Another alternative is the new hide feature, that will hide the block in the editor and omit the block in the frontend (including associated scripts and styles). See: https://make.wordpress.org/core/2025/12/01/ability-to-hide-blocks/

Or do we want to change the templateLock of stackable/price?
