Quartus II Simulator keeps old waveforms and nodes during simulation

For some reason during simulation, the signals in my .vwf don't match what are in the simulation results, and the sim results have extra/different nodes that I don't even have selected. Does anybody know why this is? I am not using certain nodes in the VWF however they appear in the results anyways.. am I don't something wrong? This is getting awfully annoying, I end up creating a new VWF to get rid of them. (See attachments for an example)
