[TYPO3-RTE] strange transformation: <div><h2>Title</h2>Text</div>

[Typo3 Ukraine]

Hi,

my current setup gets this:

<div class="memokasten"><h2>Description</h2>Each RTE may use additional 
properties for the RTE.
</div>

converted into this:

<div class="memokasten"></div><h2>Description</h2><p>Each RTE may use 
additional properties for the RTE.</p><div></div><p></p>

What I want is that the <h2> will be kept inside the <div>. I'm sure the 
original text is valid HTML and I tried googling and checking the 
documentation. But nothing seems to help. This issue is both happening 
in HTMLArea and tinyRTE. Please advice.
