This is a persistent issue, first noted by @chandra2ga in multi-looked data analysis.
The easiest fix is in the APS module - keep an array that marks the location of NaNs prior to zero conversion and then use this to re-insert the NaNs in the output after APS filtering. This should then not affect the reference pixel area.
Problem To place all interferograms in reference to a common area, a reference pixel is chosen so that the phase from this pixel is subtracted from the whole interferogram. A kernal is used for this, where the median phase of the kernal is used as the value to subtract from the interferogram.

This is currently only occurring with higher resolution processing. But could be occurring elsewhere.
