What Happened in NC's 12th House District in 2014?

With Wisconsin's gerrymandering case going to the Supreme Court, I have decided to find the efficiency gap in my state's past elections. While doing so, I ran into a weird quirk from 2014. There are two recorded results for the 12th House District. One is called "US HOUSE OF REPRESENTATIVES DISTRICT 12", the other is "US HOUSE OF REPRESENTATIVES DISTRICT 12 (UNEXPIRED TERM)". What's going on here? Which one is correct?

So let me see if I've got this right: Alma Adams was pegged as Mel Watt's replacement when his term was cut short by his appointment to Director of FHFA, but instead of having the election for his replacement at that time there was a retroactive vote for what Adams had already served as well as another vote for if she would continue. Is that right?

On a side not, District 9 did not have a Democratic challenger that year. How would you suggest addressing this? Leaving the district in just makes it seems like it was skewed in favor of the Democrats since they wasted 0 votes and republicans wasted 50%, but in reality it likely would have shown another Republican favoring gerrymander had any Democrat decided to run against the Republican there.
