Problem with making table with special header that includes bolded numbers

Question

I am the author of the question: Problem with a table with special header: bolded numbers are badly aligned with the rest of the numbers

Following Zarko's advise, I have revised my code according to his suggestion to get my bolded number aligned in the right way. However, a new problem is popping up. I am making another post because I can't share the updated version of my code in my previous post.

I am trying to make a table with special header.

I tried the following code:

\documentclass[11pt,a4paper]{article}
\usepackage[hyperref]{NAACL2019}
\usepackage[skip=1ex,font=small]{caption}
\usepackage{times}
\usepackage{url}
\usepackage{latexsym}
\usepackage{algorithm} 
\usepackage{algpseudocode} 
\usepackage{sectsty}
\usepackage{amssymb}
\usepackage{makecell}
\usepackage{multirow}
\usepackage{amsmath,epsfig,times}
\usepackage{tabularx} 
\usepackage{booktabs}
\usepackage{etoolbox}
\usepackage{subcaption}
\usepackage[utf8]{inputenc}
\usepackage{booktabs}
\usepackage{siunitx}  % <---
\usepackage{etoolbox} % <--- 
\newrobustcmd\B{\DeclareFontSeriesDefault[rm]{bf}{b}\bfseries} % <===
\usepackage{hyperref} % load this package last
\begin{table}[ht]
\sisetup{detect-weight, mode=text, table-format=1.4}
\centering
\begin{tabular}{l SS 
            S[table-format=-1.2]
            S[table-format=1.2] }
\toprule
 & \multicolumn{2}{c}{M1}

 & \multicolumn{2}{c}{M2} \
   \cmidrule(lr){2-3} \cmidrule(l){4-5}
 & {1-2} & {7-8} & {1-2} & {7-8} \ 
\midrule
A & \B{0.0021} & \B{0.0033} & -2.37 & 0.00 \ 
B & \B{0.0052} & \B{0.0042} & -1.23 & 0.67 \ 
C & 0.0960     & \B{0.0054} & -0.62 & 1.10 \ 
D & \B{0.0082} & \B{0.0057} & -0.21 & 1.08 \ 
E & 0.0107     & 0.0097     &  0.74 & 1.41 \ 
F & \B{0.0080} & 0.0088     &  5.05 & 5.05 \ 
G & 0.0140 & 0.0148 & -2.37 & 0.00 \ 
H & 0.0128 & 0.0176 & -1.23 & 0.67 \ 
I & 0.0157 & 0.0164 & -0.62 & 1.10 \ 
J & 0.0145 & 0.0155 & -0.21 & 1.08 \ 
K & 0.0205 & 0.0209 &  0.74 & 1.41 \ 
L & 0.0236 & 0.0225 &  5.05 & 5.05 \ 
\bottomrule
\end{tabular}%}
\smallskip
\caption{My Caption}
\label{tab:table1}
\end{table}

But it gives the following result:

The problem here is that there is [rm]bfb right before each bolded number, which I want to remove.

How can I resolve this issue?

PS: For my LaTeX document, I am using this specific template for a particular academic conference: https://www.overleaf.com/latex/templates/instructions-for-naacl-hlt-2019-proceedings/xyyfwfkswhth

This conference template is 2-columned, that is, the texts are displayed on each page in 2 columns.

Thank you,

You wrote,

a table with special header that includes bolded number

I can see no bolded numbers in the "special header". What I do see is a number of specious and unnecessary & symbols that are causing various issues. Remove them, and the code compiles fine.

I can also see no reason for employing the \scalebox directive -- unless, that is, you want to deliberately sabotage the look of the table. Oh, please don't load latexsym if you also load amssymb, and please don't load packages more than once.
