Error message using normality test in vars

Hi all,

I'm running a vector-time series model with the vars package.  When I 
test the univariate and multivariate normality of the residuals using 
normality(), I get the results, but also this warning

Warning messages:
1: longer object length
         is not a multiple of shorter object length in: b2 - rep(3, 4)
2: longer object length
         is not a multiple of shorter object length in: b2 - rep(3, 4)


What does this mean and do I need to worry about it.

Thanks in advance,

David
