Charles, I appreciate those guides, there were a couple of things that helped but the problem persists.

Guessed, I couldn't fully understand, I'm studying your suggestions to try to apply them but meanwhile I found the issue I believe:

I have titles up to "title 4", this means, until a 4th subsection in the first chapter, but when I go into the second chapter where I have a table in a 2nd subsection (example: 2.1), is where the problem begins. I fixed it by changing that table from chapter 2.1 in caption numbering window. The following image as reference: ChaptNum — ImgBB where in the option "Empezar con el estilo" = "Chapter starts with the style" is where I change the value to "Title 2". After doing this, my table from chapter 2.1 has its title fixed but, this also updates all the tables before that to the same configuration of "Chapter starts with the style: Title 2", so my table from chapter 1, which had a 4th title, now only show up to title 2. I read that I had to maybe do some configuration on SEQ, which I admit, don't understand much and this is what it says on the titles:

{ STYLEREF 4 \s}-{ SEQ Tabla \* ARABIC \s 4}

What I conclude is that all the titles from all chapters are linked in configuration, so when I have title 4 selected from chapter one, since in my table from chapter 2.1 there's no title 4, it shows that "Tabla 0-1" as some sort of error.

Any help is appreciated.
