HELP!: Wlist Request Function

Hello there,
I have a page set up to display a list of posts with a certain tag using the function
[wlist request= “tag=tagname”]. It’s working well for the most most recent posts with that tag, but for some reason the rest are simply not displayed. I’ve tried retagging the posts, but nothing has happened. Any ideas? All advice is very much appreciated.

Also, on that same note, I used to have another wordpress running the same wlist request scheme, but instead of just a text list of the tags, the list included prettier listings with thumbnails, titles and the post description. Any ideas how to change the format of the wlist results?

Thank you!
