Hi Adams,
Perhaps you have entered the .mat file as 'multiple conditions' instead of 'multiple regressors' for some subject/session? ('names', 'onsets', and 'durations' are the expected variables when defining multiple conditions using a .mat file, while 'R' is the single expected variable when defining multiple regressors using a .mat file)
Best
