Drawing several BeginArea inside a BeginScrollview (GUILayout) produces an unexpected behaviour

Well, I have a question with a GUILayout.BeginArea wit$$anonymous$$n a BeginScrollview.

         if (m_searchedItems?.Length > 0)
         {
             m_scroll = GlobalGUI.BeginScrollView(f_isEditor, m_scroll, viewSize);
 
             for (int y = 0; y < rows; ++y)
             {
                 GUILayout.BeginHorizontal();
 
                 for (int x = 0; x < columns; ++x)
                 {
                     // Show items thumbnails...
 
                     var tTexture = GetThumbnail(item);
 
                     Rect? texRect = null;
 
                     if (tTexture != null) // Check if the texture is available or it's being requested
                         texRect = GlobalGUILayout.DrawTexture(tWidth, tHeight, tTexture);
 
                     // The method from above returns an Nullable<Rect> of the texture. (https://i.imgur.com/pizrwji.png)
                     if (texRect.HasValue)
                     {
                         // Show title w/ marquee
                         // .... Code ....
 
                         var btnsRect = new Rect(texRect.Value.position + Vector2.up * (tHeight - 26), new Vector2(texRect.Value.width, 21));
 
                         // Show buttons
                         GUILayout.BeginArea(btnsRect, "aaaaa"); // "aaaaa" string is for a test
                         {
                             GUILayout.BeginHorizontal();
 
                             if (GUILayout.Button(m_infoTexture, GUILayout.Width(21)))
                                 GetInfo(item);
 
                             if (GUILayout.Button("Install"))
                                 DoInstall(item);
 
                             GUILayout.EndHorizontal();
                         }
                         GUILayout.EndArea();
                     }
                 }
 
                 GUILayout.EndHorizontal();
             }
 
             GlobalGUI.EndScrollView(f_isEditor);
         }

As you can see, I am trying to show a list of items wit$$anonymous$$n said BeginScrollview:

Of course, each must have two buttons to perform actions (line 30 of the code).

But, as you can see, in the image that I have attached, I have blueed the test string "aaaaa" so you can see that it is very $$anonymous$$ghlighted, w$$anonymous$$ch gives me to understand that all the BeginArea are being drawn in the same position.

But what worries me most about t$$anonymous$$s is that the buttons aren't displayed.

However, if all t$$anonymous$$s is implemented with the GUI class, instead of the GUILayout class t$$anonymous$$s does not happen.

W$$anonymous$$ch could be the problem?
