Title sections are not shown correctly (content from the previous section is shown after the title of the following sections)

Question

I'm trying to list some sections inside a chapter (let's say sections 2.1, 2.2, 2.3, 2.4 and 2.5), and in the section 2.2 I show 4 tables, the problem is that the titles of the sections 2.3, 2.4 and 2.5 are being shown before the last table that is in the section 2.2

Can someone tell me how can I fix this?

This is my code:

\chapter{Resolución de modelos}

\section{Utilice el método gráfico para encontrar soluciones al modelo ¿Es posible encontrar el óptimo?}

\section{Resuelva el problema usando el método Simplex}

# HERE ARE THE 4 TABLES

\section{Explique cada una de las bases encontradas durante la realización del algoritmo Simplex}

\section{¿Existen soluciones alternativas a la solución encontrada? Explique}

And this is the output:

All the tables should be after the title of the section 2.2 and before the title of the section 2.3

EDIT:

Here's an example of the code I'm using to produce the tables:

\begin{table}[ht]
\centering
\begin{adjustbox}{width={\textwidth}, totalheight={\textheight}, keepaspectratio}
\begin{tabular}{c c c c c c c c c c c}
\hline

# CONTENT
[1ex]

\hline
\\ [0.5ex]
# CONTENT
[1ex]
\hline
\end{tabular}
\end{adjustbox}

\caption{Iteración \#5}
\end{table}
