I'm not sure if I'm posting in the correct forum, but since the filter module is in the Drupal core...it would seem the best place to post this issue.

If someone could take a look at my Compose Tips page located at http://www.saviourpc.com/filter/tips you will see there is a duplcate entry for the following tip: "Text with line break"

Is there a way to remove this duplicate entry?

I have searched the Drupal site, but cannot find anything similar to the problem I'm having...and I don't want to go and start changing things if it's going to interfere with updates in the future. So any recommendations are greatly appreciated.

Not only does does it show up twice for all registered users, but it's even iewable by guests.

I guess...in addition to removing the duplicate entry...

Is there a way to prevent the page from being displayed to guests, as well?

Again...I appreciate any and all comments directing me to a resolution to these issues.
