Can anyone help me with this problem? Latex is skipping the numbering of the tables! The figure and my code are available below:

\subsection{Summary of Hybrid-Electric Architectures}

\citeonline{thesiszamboni} shows in Table \ref{summary_arch} a summary of the main advantages and disadvantages of the hybrid-electric architectures aforementioned. Many authors say that the parallel configuration is better at this current technology, since it is lighter when compared to the others. Besides, series architectures have great potential for the future. As the technology of energy storage systems evolves, new and more energetic batteries will be available, allowing more system electrification, which reduces the participation of engines. An example would be the use of more electric motors, such as in the distributed propulsion, which has shown great advantages due to aero-propulsive interactions, such as drag reduction and increased aerodynamic efficiency \cite{isikveren2015distributed}.

\section{Review of Hybrid-Electric Aircraft Projects}

Several manned, fixed-wing and electric aircraft have already flown, and there are already proposals to be sold. Table \ref{table_examples} presents examples of electric aircraft that had their first flight since the beginning of the millennium. On the other hand, Table \ref{table_examples2} shows other major studies and projects developments in partnership with government agencies, large companies and also new ventures.

    it is always best to provide an example that demonstrates the problem, your fragment can not be run but as a wild guess I would guess you are using the ltablex package? – David Carlisle May 14 at 21:32

    With your code fragment, if I extend it to MWE, I can't confirm your result.The tables are numbered sequentially as they are inserted in text. it seems that showed result is not produced with showed code fragment. sorry, your question is not clear what is your problem. you need to add missed information and provide complete small document, which will show your problem. – Zarko May 15 at 2:15
  • Do you happen to load the longtable (or ltablex) package? Skipping table numbers can happen as one of its side-effects. If so, see "Double increment of table counter" for a solution. (tl;dr: put the caption after \begin{tabularx}) – Inquisitive Lurker May 15 at 11:37

Let me shown my extension of your code fragment, by which I test it. I redefine column types in the first column, merge both landscape pages, since they are follows each others. I also add to the first table a table placement (also without it i can't reproduce your problem), which table placement closer to place of to their insertion.

Please test this MWE and compare with your document. You may discover your problem yourself.
