appearing in text

BS"D

I am using FCK Editor 2.64 with the relevant Drupal module and all of a sudden (in a fresh site) I am getting the following problem:

When I use the FCK editor to create a new listing on my site http://www.woswn.com boxes as shown on illustration show up in text editor field as soon as I click on the content create prompt as necessary. I do not add anything; I just open the node create and these show up.

Upon saving, 2 more such boxes appear and the message appears below each text entered via the text editor.

The HTML code created is as follows:
. If I remove this output via the plain text editor then the disappears but as members use the site they cannot be expected to remove the extraneous output.

What causes this and how can I remove this? It spoils the text output and distracts site users. Thanks.
