Works as intended on current version of Salt. I tried all options today and they all work.
I would, however, increase the inf. items option, as 99 is not enough for some crafting recipes.
EDIT: I have found a workaround of sorts. Say you want loads of wood. When you find a log, just turn the option on once and then off again. Now put the new 99 stack in a chest. Do this once more and you have 198 in your chest. Do it again and you have 297. Etc. Etc.
For money, just find a trader and bring a stack of 99 of something valuable. Sell it for loads of coins. Remember to have the inf. item cheat turned off, or the money stack will just go down to 99.
EDIT 2: Nevermind, stacks inside chests are also reduced to 99, just like your inventory
