You've got an absolutely valid point! However, the descriptions of the items are different on every site, so please text the minister for magic of your site (or whatever the leader is called on your site) with this suggestion as they are the person who can change the descriptions. 

Please ask the leader of your site.

Please have a look at the rules and guidelines of your site, there are many tips on how and where to start. On some sites (the housepoint page for example) there are little popup guides to help you get an impression (:
