Issue with wheels on Drivetrain in Modkit

Hi,

When setting up the robot in Modkit for VEX, when we try to make the proper selection of Omni Wheel in the drivetrain settings of the drivetrain block everything works fine when we choose a setting of Omni Wheel for either the front or back wheels, but when we choose a setting for the other wheels, the first selection reverts to 200mm Wheel. Is this a bug or are we doing something wrong? Is there a workaround? Is it significant?

Thanks,
Thad
