Hi,
in team-carousel.php change line 128 from
$items .= '<div class="tm-toggle-button-wrap clearfix"><a href="#" class="show-hide-bios closed" data-show="'.__("Show Bios", "swiftframework").'" data-hide="'.__("Hide Bios", "swiftframework").'">Show Bios</a></div>';
to
$items .= '<div class="tm-toggle-button-wrap clearfix"><a href="#" class="show-hide-bios closed" data-show="'.__("Show Bios", "swiftframework").'" data-hide="'.__("Hide Bios", "swiftframework").'">'.__("Show Bios", "swiftframework").'</a></div>';
Let me know if that worked!
