3 Column page with Left/0 and right/2 section-subsection-subsubsection numbering issues

Question

Good day

I may be doing this completely wrong, but I am trying to learn to write a form of process/workflow/framework. I am using a three-column page format, trying to keep the same section per page where:

1. left/0 column has a section, subsection, and subsubsection with a continuous numbering scheme.
2. center/1 column a graphic workflow.
3. right/2 column has subsection, subsubsection, and items. (here the numbering scheme is not subsequent from "left/0 column")

What could I be missing or doing wrong?

Any help to help me understand what I am doing wrong or what package I should look into to figure out my mistake will be appreciated.

Thank you.

\subsection{Quick Change Task Overview}
\subsubsection{Creation}
\begin{enumerate}
\item Task is created from a closed ETSR
\item Alternatively, Standards team members can submit a request.
\item Also automatically created as part of a Project if the “Create Quick Change” checkbox is checked when creating development tasks during Planning.
\item Status = Submitted.
\end{enumerate}
\subsubsection{Assignment}
\begin{enumerate}
\item Standards Manager sets Assigned To, approver, and publisher, as well as other assignment details.
\item RTL is responsible for defining assignment details for quick-change tasks that are part of a project.
\item Status changes to assigned
\item Alternatively, standards manager can close right away
\end{enumerate}
\subsubsection{Development}
\begin{enumerate}
\item Assigned to drafts the deliverables to meet the scope of the request.
\item Assigned to resolves the quick-change tasks and adds resolution details
\item If development, status changes to under review
\item Other resolution options include moved to dashboard, deferred, duplicate, not accepted, and no longer needed; status changes to closed.
\end{enumerate}
\subsubsection{Assignment}
\begin{enumerate}
\item The quick-change tasks process does not include a peer review.
\end{enumerate}
\subsubsection{Approval}
\begin{enumerate}
\item If approval is required (decided by standards manager during assignment), the approver reviews the quick-change task and adds approval details.
\item If not approved, quick-change task is assigned to, status changed to assigned, and the process repeats.
\item If approved, status changes to awaiting publishing.
\end{enumerate}
\subsubsection{Publishing}
\begin{enumerate}
\item Publisher moves the completed deliverables to the appropriate publication location and adds publishing details.
\item Status changes to published.
\end{enumerate}
