Problems with biasCorrection with LOO in some months

[MariaMercedesPoggi]

Hi climate4R group!
I'm having trouble running the biasCorrection function for my dataset, which has information of a sesonal model for the May-Jun-Ago. The error that arises is: "Error in if (any(years < min(all.years) | years > max(all.years))) { :"
I share a mini example, where the same error appears:

data(VALUE_Iberia_pr)
y <- VALUE_Iberia_pr
data(NCEP_Iberia_pr)
x <- gridArithmetics(NCEP_Iberia_pr, 86400, operator = "*")
y.feb <- subsetGrid(y, season = 2)
x.feb <- subsetGrid(x, season = 2)
cal <- biasCorrection(y = y.feb, x = x.feb, precipitation = TRUE, method = "eqm", wet.threshold = 0.1, cross.val = "loo")

I've been tracking down the error, but didn't have much luck. Any help is welcome! Thank you!
