Unable to lock things down by expansion

[Veltira]

I have tried for four days to lock everything down to classic on my server. I've tried numerous things i found on this forum through the search feature and so far I can lock down classes, races, and zones to classic. However, features from other expansions are still available. Such as the books of knowledge being in, augments dropping, etc.

I have tried changing the Variables table Expansions setting. I have tried changing the rules_values table World:ExpansionSettings setting. Both of those I've tried 1 and 0, neither works.

I'm attaching screenshots of the respective tables. Any help is greatly appreciated!
