PPk no base rover data shown

[Bill Eggers]

I usually DPOS all my "important" points like control and boundary to get a check on the RTK. When I look at the point reports and pick the summary button at the bottom left for RTK fixed the result is the base rover data. Sometimes the PPK fixed column has no results when the summary button is pressed.

Any idea why there is none? I had other points in the same project (different day) that did show results for the PPK column.
