Bug? Certain frequencies excluded from TonePattern?

I want my OBi202 to generate an approximation of the standard North America off-hook tone (howler tone in Obi parlance.) It is specified as 1,400 Hz, 2,060 Hz, 2,450 Hz, and 2,600 hertz in 100ms bursts. The device appears to be limited to three simultaneous tones, so fine, but as I'm troubleshooting the configuration, it seems that at minimum, for some reason a 2,060 Hz tone is disallowed.

Is this a bug or a feature?

This pattern works fine playing both 440 Hz and 2,600 Hz:

440-18,2600-18;-1;(.1+.1)

But change the 2,600 to 2,060 and only the 440 plays!

440-18,2060-18;-1;(.1+.1)
