I haven't tried starting from 100Hz or 1kHz and have taken down the test setup. May recreate later as time permits.
I can say that I have also seen this issue crop up, and on data points further into the sweep, when scanning from 300mHz to 300kHz with 1Hz maximum measurement bandwidth. The amplitude table may have been set differently as well for those scans. Sorry that I did not save an APC file for them. One sweep had two data points in it with -120dB gain and 0° phase.
It's honestly not a huge deal but would be nice to close out. Hope it's not too hard to recreate... although unfortunately, it does not happen every time.
