Is there a problem with the rational down sampler in the channel analyzer?

Add test source
Set delta to 100k and bits to 16 to generate a tone at 100k
Add channel analyzer and enable markers and peak measurement - it shows a tone at ~100kHz - which seems correct

Enable the rational downsampler

And the bandwidth of the spectrum is halved, as I'd expect, but the tone is at ~50kHz, which I'm not expecting.
