Heya,
I've looked through the mod, sand is produced as "sand-ore", glass is "glass-plates".
Stone being smashed into sand is still the same sand-ore that is mined.
Most likely there is some mod (QoL or otherwise) is creating the conflict with F+ . Checking your order of the mods, and disabling them and then resyncing a save is your best bet.
This mod, self contained by itself works without issue.
