gg_rsm() y axis not decoded

Hi,
I've made some rsm graphs, and it works perfectly, except that the y axis is not decoded, so it still displays either x1 or x2 or x2, etc... I've tried using ylab but it only changes the last graph. Here's an example code:

girder_experiment$group <- sample(c(1:4), size = 36, replace = T)
girder_coded <- coded.data(girder_experiment)
girder_rsm <- rsm(response ~ SO(x1, x2, x3), data = girder_coded)
plot <- gg_rsm(girder_rsm, ~ x1 + x2 + x3, filled = T, decode = T, n_columns = 3)

I've noticed that the values of the plot
plot[[1]][["labels"]][["x"]] is empty, while
plot[[1]][["labels"]][["y"]] contains the coded values. The caption that usually contains the at information also includes the x axis label, masking the error. I've managed to "fix" this by substituting these values manually. I don't know enough to find out where this arises, however...
