The correct bitmask for Velious is 3. Bitmasks are a bit unintuitive, but with the value of 2 you enabled Velious but disabled Kunark. You need to add all bit values together to get the mask. So, Classic=0, Kunark=1, Velious=2, add them all together for the mask of 3.
(For more info, check the values in the bottom table here:

If Bots:BotExpansionSettings wasn't in the DB it sounds like you don't have bots enabled on your server, so that's fine you can ignore it.
So the values you want for Velious are:
1. VARIABLES | Expansions | Bitmask | 3
2. RULE_VALUES | Expansion:CurrentExpansion | Bit | 2
3. RULE_VALUES | World:ExpansionSettings | Bitmask | 3
