Unwanted indentations ONLY in the first row of longtable

Question

I have a lot longtables in my work and I figured it out that ONLY the first row of the first column is indented. It doesn't occur in the rest of rows. I saw that with another type of tables (like tabular), that are smaller, my problem doesn't occur.

I was searching how to fix it, I found this post, but the solution didn't work for me. left alignment of longtable - unwanted minimal indent

I painted the error in blue. I want the first row exactly equal than the second one.

Anyone who knows how to fixed it?

Thanks very much in advance.

Sorry I forgot to add an image of my error. I painted in blue. It's the indentation that I don't want. — emr2, Aug 28 '20 at 16:41

The problem is with \label{tab:CasosDosVarHom}. You must add a % after the argument of \label (at the end of the input line). Otherwise, it produces a stray space.

See What is the use of percent signs (%) at the end of lines? (Why is my macro creating extra space?)

Oh well spotted (+1) I thought @Eva meant the Foo row by "1st row" so I was looking in the wrong place:-) Actually it's probably safer to put the label inside the entry (eg mutirow works by accident after \label but \multicolumn would give an error. — David Carlisle, Aug 28 '20 at 16:48

I would reorganize your table preamble. Mowing \label immediately after caption solve your problem:

Other small changes in your code make table more consistent (added lines at end of the each part of table, information that table continue on the next page, enabling table break only at begin of multirow cells).

+1!!! Thanks so much for giving me extra advices about my code! I’m learning LaTeX and I don’t really expert at this.
I need to ask you some questions about your changes:

How can I organize the preambule packages? I usually see people that put a lot of packages but I don't really know how many can I introduce in one bracket.

A4paper + hmargin = 2.5 and vmargin = 2cm are exactly the same measures that I had? Because I need my master’s thesis to have margins of 2 cm (top and bottom) and 2.5 cm (left and right). But I didn’t put nothing about A4…. — emr2, Aug 29 '20 at 08:31
Dear @Eva, you are welcome! BTW, if an answer solve your problem on the best way, you can accept it (by clicking on check mark at top left side of answer). As I see, so far you not accept any from received answers :-(. — Zarko, Aug 29 '20 at 10:07
@Zarco Can you explain me the two questions that I asked above? (Thanks in advance!) — emr2, Aug 29 '20 at 10:16
@Eva, you can accept only one answer from among received to question. On this your question you decided, that the first answer better fulfill your expectation that mine ;-). If you have further questions, pleas ask them as new questions. — Zarko, Aug 29 '20 at 10:19
@Zarco Both answers help me a lot. For that, I wanted to acepted both :( Your question solved some problems that I didn't know if I can solved. — emr2, Aug 29 '20 at 10:22
