[TYPO3] tt_news seting template

[Nino]

Hi,

I'm using tt_news template tab to set the news template but if i make a 
change to the template i have to delete the current one in template tab and 
set the new one, which sometimes gets name like news_template#some_number. 
How to avoid this behaviour.. i don't want to delete/set template for every 
change i make to the news template. I tried to clear the cache but that 
didn't help? Should i set the template TSetup? Thx.
