The problem is here:
cin >> options;
You can only extract (>>) from cin when the user hits enter. So the user types 1 Enter and that line executes. Since options is a char, it extracts a single character (1) from cin and stores it in options. The Enter is still in the stdin buffer, since nothing has consumed it yet. When you get to the getline call, the first thing it sees in the buffer is the Enter, which marks the end of input, so getline immediately returns an empty string.
There's lots of ways to fix it; probably the easiest way that fits with the model you're using in your program is to tell cin to ignore the next character in its buffer:
cin >> options;
cin.ignore();
