This is clearly a software bug, not an idea.

When I create a brochure in Acrobat DC, it automatically changes the groupings of text boxes, making it difficult to make future modifications. How do I make it retain the text boxes as I built them? It is less of a problem if it separates a text box into two boxes. It is a big problem when it arbitrarily combines two or more text boxes into one.

It occurs randomly. On some brochures that I create, they retain the original structure when I open them again for further editing. On others, the next time I use the file, one or more groupings of text boxes have changed. I cannot discern a pattern. All the brochures are similar in design, layout, font, graphics, size, etc.

In the attached file, you can see 3 such instances. Originally the blue text "All the Power..." was in a text box separate from the list (Whiteboard, etc.). The blue text "All the Security..." was also in a separate text box. For some reason, it was combined with the "End to End..." and "All Meetings..." Originally, the entire line "No Data...to Meetings Deleted" was in a single text box. When I re-opened the file and clicked edit this evening (only saved yeserday), the software had made all of these changes as well as one other on the second page.
