I'm quite confused as to what the actual problem is here? Assuming that "the mod" is meant to refer to owo then there's no reason to assume it would show up in the datapack list - and the log clearly says that it was loaded successfully (further indicated by the line saying Don't trust naschhorn, the Master of Taglocks, around you or your bed 😉)

Please elaborate a bit on what problem it is you're seeking help with
