브라우저 및 모바일 환경은 확인했는데 문제가 없네요ㅠ

10명 정도의 사용자에게 확인해보니 모두 카테고리2에 있는 C만 체크하고 카테고리1에 있는 B는 체크하지 않았다고 합니다. (그런데 작성된 글에는 카테고리에 B와 C가 기록되어 있습니다.)

제가 카테고리1과 2를 체크박스로 바꾸기 위해 아래의 코드를 사용했는데요..

/*kboard category select box to checkbox*/
add_filter('kboard_get_template_field_html', 'kboard_get_template_field_html_20201210', 10, 4);
function kboard_get_template_field_html_20201210($field_html, $field, $content, $board){
	$meta_key = isset($field['meta_key']) ? $field['meta_key'] : '';
	$field_name = (isset($field['field_name']) && $field['field_name']) ? $field['field_name'] : $field['field_label'];
	$required = (isset($field['required']) && $field['required']) ? $field['required'] : '';
	
	if($meta_key== 'category1' && $board->id == '5'){
		ob_start();
		?>
		<?php if(!$board->isTreeCategoryActive()):?>
			<?php if($board->initCategory1()):?>
				<div class="kboard-attr-row <?php echo esc_attr($field['class'])?> <?php echo esc_attr($required)?>">
					<label class="attr-name" for="<?php echo esc_attr($meta_key)?>"><span class="field-name"><?php echo esc_html($field_name)?></span><?php if($required):?> <span class="attr-required-text">*</span><?php endif?></label>
					<div class="attr-value">
						<?php while($board->hasNextCategory()):?>
							<input type="checkbox" name="category1" value="<?php echo $board->currentCategory()?>"<?php if($content->category1 == $board->currentCategory()):?> checked<?php endif?>>

						<label class="attr-reset-button" style="cursor:pointer;display:none;" onclick="kboard_radio_reset(this)">초기화</label>

					</div>
				</div>
			<?php endif?>
		<?php endif?>
		<?php
		$field_html = ob_get_clean();
	}
	
	return $field_html;
}


add_filter('kboard_get_template_field_html', 'kboard_get_template_field_html_20201210_1', 10, 4);
function kboard_get_template_field_html_20201210_1($field_html, $field, $content, $board){

	return $field_html;
}

예를들어 B와 C를 체크했다가 B를 체크해제한 경우라든가.

C만 체크했는데 C와 B가 선택되었다고 기록될 수가 있을까요?

남겨주신 코드만 봤을 때는 

딱히 이상한 점을 발견하기가 어렵습니다.

파이어폭스 등의 다른 브라우저와

모바일 환경에서도

각각 테스트 및 확인 해보시겠어요?

고맙습니다.
