Hi Nikki,
Unfortunately this is the standard behaviour of Salesforce.
Currently, when there are Attachments on a Task or Event that is related to an Account, Contact, or Opportunity, those Attachments will roll-up to appear in the Notes & Attachments related list on the Account record.
However, the attachment does not appear in the Notes & Attachments related list on the object itself (that the task is related to). It only shows on the related Account record if it is a Contact / Opportunity that the task is related to.
I would recommend you to vote and promote this Idea.
