Columns stacked on top of each other

[StuYuXu]

Hello, friends.
The package you developed works really well, but for some reason, the columns on the right side of my image are stacked together.
My code is
`library(sankeyD3)
nodes = data.frame("name" =
c("a", # Node 0
"b", # Node 1
"c", # Node 2
"d",
"e",
"f",
"g",
"test",
"test1",
"test2"),
"PosX"=c((7389-5950),
(7389-3900),
(7389-7389),
(7389-4505),
(7389-4049),
(7389-3000),
(7389-2222),
(7389-2222),
(6000),
6000))# Node 3
links = as.data.frame(matrix(c(
0, 5, 0.066, # Each row represents a link. The first number
1, 5, 0.025, # represents the node being conntected from.
2, 5, 0.909, # the second number represents the node connected to.
0, 4, 0.9,
3,4,0.1,
4,6,1,
5,7,1,
7,8,1,
7,9,1),# The third number is the value of the node
byrow = TRUE, ncol = 3))
names(links) = c("source", "target", "value")

sankeyNetwork(Links = links, Nodes = nodes,
Source = "source", Target = "target",
Value = "value", NodeID = "name",nodeStrokeWidth =5,
fontSize= 12, nodeWidth = 5,NodePosX="PosX",iterations=32,dragX=T,dragY=T
)`

The output is

Hope you can help me, thank you!
