I took some liberties here, and check my spelling (is "erstellt"?)
How about<$link/> <span style="font-size:0.7em;color:rgb(144, 238, 144)" > {{!!erstellt}}</span>
instead of
{{!!title||$:/core/ui/ListItemTemplate}}@@<span style="font-size:0.7em;color:rgb(144, 238, 144)" > <$transclude field='erstellt'/></span>@@
I think getting the title with that transclusion template adds a line-feed/carriage-return before displaying the date.
