Found bug in the theme

Hello i use the travelify theme and really like it but i had an issue and in the categories pages the title was shown double I did not figure out and ask my freine Esther Nowack webdesigner from Berlin and she found the bug that solved my problem. May be you can fix it in the next update? I change the core theme file for me now but i guess others will have the same issue. Here the solution
In library/structure/content-extension.php muss in Zeile 119 hinten der Teil mit dem title entfernt werden , so dass die Zeile dann heisst:
$image .= ‘‘;
