You should probably delete fullrun_ccd3_acisf11752_pi14-548_cl_pass0_tfrozen_src56_1.ximg
Either tweak this fit manually starting from fullrun_ccd3_acisf11752_pi14-548_cl_pass0_tfrozen_src56.ximg or adjust the simplespatial fit parameters in $XASSIST/data/missions/*/*/spatial.dat and re-run simplespatial fitting after setting file recreation parameter to yes
