Missing overlaps in euler plot

[bakerwm]

Is there a way to fix the following problem?

In the following example, missing area A&B (12) in euler( ), but works in venn( ).

# R code
x <- setNames(c(164, 561, 166, 12, 459, 703, 162), nm = c("A", "B", "C", "A&B", "A&C", "B&C", "A&B&C"))
plot(euler(x), quantities = T) # A&B removed
plot(venn(x), quantities = T) # A&B present

find out that, A&B area fitted value is 0, could be the reason.

Same problem here, and even worse, none of the overlaps were shown:

And when plotting it, I only got 4 un-adjacent circles.
