So i used the settings "Blockstoavoidbreaking" to not break glowstone, yet when using sel replace command on a selected area, it will still break glowstone to achieve it's goal.

to be clear im not using sel replace to replace glowstone, im using it for melon blocks

BlocksToAvoidBreaking is, as the name says, a list of blocks to avoid breaking. If it seems that the goal cannot be achieved by another path, it will break those blocks. Please close this issue, this is not a bug, this is intentional.
