What could be causing the problem (Jevix)?

Question

HTML

In general, there are articles, they are written in tinyMCE , and he, in turn, sets the line break (created by pressing ENTER) with the tag , but not just because of which Jevix perceives them (as it seems to me) as closing and creates each couple. As a result, all line breaks are doubled , and then, if I re-edit the article, then for tinyMCE they are displayed as after saving again, all tags are paired! And on Jevix it seems to spit on the line How to solve this problem? <br><br><br /><br /> => <br><br /> <br><br /><br /><br />
$jevix->cfgSetTagShort(array('br'));
