Multi-plot y-data error for rel_flux_T1

I keep getting a weird error when I try to plot my target star data for an exoplanet transit light curve. After selecting my target and comparison stars, all the windows pop up fine, but in the measurements plot, all the target star data (in blue below) stays flat along the bottom of the plot (look just above the x-axis) and I can't get it to normalize to one with zero shift.
 

In the Multi-Plot Y-Data window under "then Shift" for this particular target star's row, a black diamond with a question mark appears when all the plot windows open up:

This happens for all the data sets I have tried to analyze.

When I try to change the value to zero, I can change it, but nothing happens on the plot and my Mac makes the "forbidden action" thumping noise.

Has anyone experienced this? If so, any idea how I fix it?
