TPS65400-Q1: webbench uses other switching frequencies than what was specified

Part Number: TPS65400-Q1


i'm trying to verify/set the design parameters for a set of voltage rails:

3.3v at .3a

1.2v at 2.5a

1.8v at .5a

2.5v at 0.1a

when i try to set the switching freq to 2.1mhz, it accepts this value, but when it recalc's the data, it uses a 150hz and a 66khz for two of the rails (3.3 & 2.5 rails).  the other two rails are at the expected frequency.  is there a way to override this?  it's a bit hard to come up w compensation values with these goofy frequencies...
