mass values in flavor combination do not coincide

Hello,

I am trying to test the Littlest Higgs model.

I generated some processes and WHIZARD keeps complaining like this:
******************************************************************************
******************************************************************************
*** FATAL ERROR: Process 'ththbar': mass values in flavor combination do not coincide.
******************************************************************************
******************************************************************************

What does this mean? What did I type wrong?

Thanks!

Sincerely yours,
So Young
