Custom Field Option Missing

I have noticed that the custom field option seems to be missing in the newest version. I have added it, and seems to be working fine. See code below.

<select name="top_opt_custom_hashtag_option" id="top_opt_custom_hashtag_option" onchange="javascript:return showHashtagCustomField()" style="width:275px;">
									<option value="nohashtag" ' . top_opt_optionselected('nohashtag', $custom_hashtag_option) . '>' . __('No. Don\'t add any hashtags', 'Tweetily') . '</option>
                                                                        <option value="common" ' . top_opt_optionselected('common', $custom_hashtag_option) . '>' . __('Yes. Use common hashtags for all tweets', 'Tweetily') . '</option>
									<option value="categories" ' . top_opt_optionselected('categories', $custom_hashtag_option) . '>' . __('Yes, Use hashtags from post categories', 'Tweetily') . '</option>
									<option value="tags" ' . top_opt_optionselected('tags', $custom_hashtag_option) . '>' . __('Yes. Use create hashtags from post tags', 'Tweetily') . '</option>
									<option value="custom" ' . top_opt_optionselected('custom', $custom_hashtag_option) . '>' . __('Yes. Create hashtags from custom fields', 'Tweetily') . '</option>
