Bugged Translation

Hi,

After i activated Pro version (yes i install it correctly, twice) via guide.
I Translating via Loco plugin and some my translated strings are reverted + can’t translate them.

1) The Average score is.., Result (backend).
2) Details in user statistic on frontend “missing string in pot file”.
3) User statistic frontend “18:45:34 Feb 14, 2020 18:49:59 Feb 14, 2020”, Feb like February is good, but not variable.

Where i can translate months or remove names and make classic date format 14.2.2020, 14/2/2020 vice versa?

I managed to translate Details and AVG score, via php files, but i think next update rewrite them.

/*
         * Average statistical of quiz
         *
         * Checking enabled or diabled
         */
        if (isset($options['enable_average_statistical']) && $options['enable_average_statistical'] == "on") {
            $result = $this->ays_get_average_of_scores($id);
            $show_average = "<p class='ays_average'>" . __('**THIS **The average score is', $this->plugin_name) . " " . $result . "%</p>";
        }

 if ($show_result_report) {
                $user_page_html .= "<td><button type='button' data-id='".$id."' class='ays-quiz-user-sqore-pages-details'>".__("** THIS (Details)** Více", $this->plugin_name)."</button></td>";
            }
            $user_page_html .= "</tr>";
