Questions on Coach bag series?

Hi, I am new to this brand and recently bought some bags from them, then I tried to look them up in their official website but could not find any info on the bags I purchased. The website listed all the series such as Madison, Poppy etc. Buy mine are called Gallery signature tote and Daisy floral graffiti. Why are they not listed on the website? I think they are beautiful but are they not listed because they are outdated？ Or Coach just does not show everything they have on their website(which is unlikely)? Really need a Coach expert to clear this up. Thanks in advance.
