Doesn't convert tokens from Custom Formatters

I have created a custom formatter with the following code:

<div class="image-with-caption">
<div class="image"><img src="[site-url]/[filefield-imagecache-square-thumbnail]" alt="[filefield-alt]" title="[filefield-title]" /></div>
<div class="caption-box"><span="caption"><a href="[site-url]/node/[node-nid]">Description: [field_image-filefield-description] Size: [field_image-filefield-filesize_formatted]</a></span></div>
</div>

when using insert to insert an image with the above formatter, it will render into the following:

<div class="image-with-caption">
<div class="image"><img src="http://www.example.com:8080/sites/www.example.com/files/imagecache/square-thumbnail/Albert_Einstein_Head_Cleaned_N_Cropped_1.jpg" alt="fdfdafasdfdasf" title="fdfasdfasf" /></div>
<div class="caption-box"><span="caption"><a href="http://www.example.com:8080/node/">Description: [field_image-filefield-description] Size: [field_image-filefield-filesize_formatted]</a></span></div>
</div>

The code changes some of the tokens, but not all. I have inserted the same code through linodef and it is able to format the above two missing tokens correctly. Though it has a similar problem with the alt and title tokens.
