[Plugin: List category posts] stopped working properly

I was using wordpress vision 3.3 and just before latest version of [Plugin: List category posts] and at first it was working fine then randomly the pages that were meant to display the categories now show the wrong ones..

On my page imdb top 250 i want to display the movies i have reviewed in that category named “top 250”
so i used the code
[catname =top 250]
-that works-

now what doesnt work is when i want to display all the genres on my page
“genre” is the parent catergory of all the different movie genre pages (comedy, thriller, etc)
the code i used was:
[catname =genre]

now this used to display the right information(comedy, thriller, etc in a list) but now its given me random posts in the different catergories (Not even all of them just some random ones)

my site is http://www.midnightreview.co.uk
check out the “genre” page and you will see my problem

Thanks in advance for any help!

p.s. i have updated both wordpress and the plugin and it didnt make any difference
