When I was making redstone systems with replace blocks to air, it doesn't do this.
I'll explain:
When for example I want ONLY make stone replace with air, and I type /setblock [coords] air 0 replace stone 0 ; it doesn't fit only for stone, it's just the 'replace' tag is not added. With this when I fill area with slime block and I want to delete only the stone blocks and type in this way the command, but fill not setblock, it deletes the slime blocks too :/
Please fix that if you can. Thanks in advance! 🙂 And sorry if I have mistakes anywhere...

The replace option doesn't replace specific blocks. If you want to replace specific blocks use the /fill command.
