FCK adds <p></p> with <a href....

Hi, pls help me.
I use the czech free redaction system and I added there FCK editor.
BUT if I can add link in sentence, its generates <p> tags around 'link word'.
Example:
I wrote:

Sem vlozte prislusny text vcetne HTML <a href="http://url.cz">syntaxe<a/> nebo v pripade nevyuziti teto casti vse vymazte - tedy vcetne tohoto textu!

And its generated:

<p>Sem vlozte prislusny text vcetne HTML</p>
<a href="http://url.cz">syntaxe </a>
<p>nebo v pripade nevyuziti teto casti vse vymazte - tedy vcetne tohoto textu!</p>

It looks that:


Anyone know how repaired it?

Btw. Sorry for my English.
