Which other mods do you have installed? Is this a scan you made yourself?

https://pastebin.com/qiYxeD01 Possibly a custom scan. Playing Engimatica Expert mode. i dont know of any mods that make bedrock harvestable... but the pack does have flat bedrock

If it is a custom scan you could just remove it from the JSON. Don't know why it would list it, but to be honest I don't really care about that type of oddness in the scans.
