Absolutely LOVE this plugin but can you help us quick?!

Been looking for a plugin for ages like this here is my site: https://yont.co.uk/

as you can see I have a mainly image site for my facebook pages but all my image posts are uncategorized and all the text ones in a category, I tried to put uncategorized in the category id but did not work is there away around this? or disallow the text category?

Please help!

Thanks Sam.
