Hi Gavin,
I'm not really sure what may be going on, but I noticed the transit fit is not converging (the red boxes around the fit results). That may be because the inclination is "locked". Try unlocking it and see if that helps. There are also a lot of detrending parameters selected. In general, I'd only use meridian flip with one other, or at most two others. The time series is really not long enough to support more than that (especially with the limited OOT.
As far as the comp light curves, the jump in the data is fairly large and may just be outside the range AIJ is checking. However, there are two detrend modes, so go to Multi-plot_Main->Preferences and try the opposite mode that you have set to see if that helps:
