tab expands every time to stupid tags

Hello,

when typing stuff like this: aöklsdjföksajö and hitting tab the stuff expands to: <aöklsdjföksajö></aöklsdjföksajö> ... So it is impossible to tab throu the Variables of the life templates ... every time i fill out the variable with some text and hit tab to switch to the next variable my text expands to such stupid tags. in zen coding the same problem: this line:
ul>li*5
expands correct to

<ul>
 <li></li>
 <li></li>
 <li></li>
 <li></li>
 <li></li>
</ul>
but when i try to tab throu the <li>-Tags and type text, i get stuff like this:

<ul>
 <li>
some <content></content></li>
 <li></li>
 <li></li>
 <li></li>
 <li></li>
 </ul>
