If you didn't change the amount of salt in the rub, I think this is likely your problem. Did you happen to take note if the meat from walmart was "enhanced?"
Some places sell enhanced pork, which ultimately means it has been injected with a solution which is high in salt content in an attempt to make it juicier and less likely to dry out for the average consumer. So, if you happened to get an enhanced butt for your second go and it came out overly salty, that would most likely explain it.
