Wordpress plugin shows item multiple times if it has more than one category

Hello, thanks for that nice jplist wordpress plugin. It works quite well except it shows items more than once if they are listed in more that one category. Is there a way to correct this behaviour?
Thanks for your reply and your support.

The issue is about duplicate items in the jPList WordPress plugin when an item belongs to multiple categories. Start by examining the plugin's PHP files that handle category queries and the jQuery sorting/filtering logic. Look for where items are fetched and rendered, checking for duplicate entries in the data source. Test with a WordPress installation that has posts in multiple categories to reproduce the bug.
