Change Tab-order

Hi, i cant find how to change the order of the tab (the diamomd-like tabs)

i tried to change the “Eventcategory” setting to order by id, but snitt nothing.

the thing is that the tabs is shown in eatch other.
tab 1, shows also tab 2, and tab 2 shows tab 2 and 3…
so samtning is wrong and i cant find out what.

edit 1:
if i remove this .$short_content. in page-element.php the error
disappear. so i think it is somthing with the code that shorten the text.

edit 2:
if i change
$short_content = substr($event_content_to_short, 0, $num_of_characters);
to
$short_content = substr($event_content_to_short, 0, 1000);
then its showing correcty again.
Think that the content from the page is corrupting the tabs
