MANOVA.RM Returning Inaccurate Averages in Descriptive Statistics

I am having issue with the mult.RM function. I am running a within subjects multivariate ANOVA with two DVs (width and number) and three IVs (niche, class, and position). The within subjects sampling criteria is position. The code is running well and the formula is correct. However, I am finding discrepancies between the average DV's generated by the code's descriptive statistics and the actual averages.
For example:
For, class A , niche d, position 1 the output generates an average of 134.500 for width and 47.000 and for number.
Calculated by hand class A, niche d, position 1 should be an average of 45.3 for width and 107.2 for number.
Where do these descriptive statistics come from? Why are they so different than the actual averages?

Code:

library(MANOVA.RM)
specimen<-EA_MANOVA_for_R$individual
niche<-EA_MANOVA_for_R$light niche
number<-EA_MANOVA_for_R$INL cell Number
width<-EA_MANOVA_for_R$INL Width
class<-EA_MANOVA_for_R$Class
position<-EA_MANOVA_for_R$retinal position
dataset<-data.frame(number, width, class, niche, specimen, position)
fit<-multRM(cbind(width,number)~class * niche * position, data = dataset, subject = "specimen", within = "position")
summary(fit)

Output:
