Strange SALPA GUI behavior

What steps will reproduce the problem?
1. Train noise levels
2. Select SALPA
3. Press Start

Here are my HW Settings:

** General Settings ** 
  ADC Polling Period (sec):       0.1
  DAC Polling Period (sec):       0.1

** Raw Voltage Input ** 
  No. Channels: 64
  Samp. Freq (Hz):                25000
  Amplifier Gain:                 1200
  A/D Gain:                       2X 

** Spike-Pass Filter ** 
  No. Channels:                   64
  Samp. Freq (Hz):                25000
  Low Freq. Cut (Hz):             300
  High Freq. Cut (Hz):            5000
  Filter Order:                   3
  Filter Type:                    Butterworth 

** Auxiliary Digital Input ** 
  No. Bits:                       32 
  Input Port:                     Dev2/port0
  Samp. Freq. (Hz):               25000

** Auxiliary Analog and Digital Outputs ** 
  No. Digital Bits:               32 
  Dig. Output Port:               Dev1/Port0 
  No. Analog Channels:            4 
  An. Output Channels:            Dev1/A0-3 
  Samp. Freq. (Hz):               100000.0 

** Selected Recording Streams ** 
  [ ] Raw Electrode Voltages 
  [ ] Spike-band Filter 
  [ ] SALPA Filter 
  [ ] Spikes from Raw 
  [ ] Spikes from SALPA 
  [X] Fully Processed Spikes 
  [ ] Electrical Stimuli 
  [ ] LFPs 
  [ ] MUA 
  [ ] EEG 
  [ ] Aux. Analog Input 
  [X] Aux. Digital Input

What is the expected output? What do you see instead?

I expect SALPA to filter the raw data streams, but when I press start, the 
SALPA checkbox deselects itself and no filtering is performed. If this is 
because SALPA requires some auxilary data (e.g. stim trigger times) to work, 
then the user should be informed of this and told to select that data stream in 
hardware settings before using SALPA.
