Unwanted blank space in ADE

[#1]

Hello

I have a problem with a ebook in epub format. It happens that in Adobe Digital Edition a blank space appears between a couple of paragraphs after a large amount of text. I checked in the xhtml file and there is no such space, in the css file the <p> tags have only one defined magin-top: 0.1875em;  page-break-after:auto;

page-break-before:auto; do not understand why a large space is created from nothing. I assume it has to do with how ADE organizes the text that shows, the reflux of text, will that be?

I sincerely appreciate the answers you can offer me

This problem is not the first time it happens with ADE, every time it comes from several full text views it suddenly does that, and in medium size it even inserts a page break when the style of the paragraph does not say that.
