¿Por qué cuando elimino la última columna, se superpondrá en la tabla?

Question

Básicamente, quiero eliminar la última columna que indica "BCa 95\% Intervalo de confianza de la diferencia".

Cuando cancelo a continuación:

& \multicolumn{1}{>{\centering\arraybackslash}p{8em}}{\textbf{BCa 95\% Confidence Interval of the Difference}} 

se convirtió:

Solo quiero tener una tabla que se muestra a continuación,

\usepackage{seqsplit, caption} %for table spacing to second row
\usepackage{booktabs, ragged2e} % Use booktabs rules and get rid of vertical rules, ragged2e to ragged text
