Hmmnoo...
This is happening in R code, and the error is the same as you'd get from

Error in factor(1, levels = 1:4, labels = 1:5) :
invalid labels; length 5 should be 1 or 4
So, not going into the actual code, I would suspect that it is
encountering a problem where a user format has values and labels out of
sync. This could well be a bug in the package(s), but I wouldn't rule
out that your data could have gotten into some inconsistent state. You
might try debugging to the trouble spot and see what is actually in
f$value and f$label at that point.
