Why is my CrossTable not square? gmodels package in R - r

Question

I don't how it could ever not be square, but here is my code.
It is making me type more, though I do not think there is anything else that makes sense to type. It is missing the "-11" id column, but it is not missing the "-11" row. It does not include the numbers from the "-11" column in the total column. Though, as you can see, where the total row and total column intersect, the overall total is correct.
Any input would be appreciated.
(the csv is from https://www.kaggle.com/marianna13/starter-particle-identification-from-94dec2e4-9)
library(class)
library(tidyverse)
library(gmodels)
particle <- read_csv("C:/Users/laura_000/Documents/joe/ML with R/pid-5M.csv")
particles <- particle[sample(nrow(particle), 50000), ]
particles_train <- particles[1:45000, 2:7]
particles_test <- particles[45001:50000, 2:7]
particles_train_labels <- particles[1:45000, 1]
particles_test_labels <- particles[45001:50000, 1]
particles_test_pred <- knn(train = particles_train, test = particles_test, cl = particles_train_labels[,1, drop = TRUE], k = round(45000^.5))
CrossTable(x = particles_test_labels[,1, drop = TRUE], y = particles_test_pred, prop.chisq=FALSE)
Here's the output
