Crest Factor measurement wrong

When I measure the crest factor of a sine wave, the crest factor measures 2.865. The crest factor of a sine wave is 1.414. It appears the software is calculating RMS to peak to peak value isntead of RMS to peak.
It is off by a factor of 2.
Pico Scope 2200 series software 5.13.9.

Anyone else seen this?
