Hello and welcome.
You have the option to remove offers from the pending list:

At the end of each offer, you'll see a "Remove" button. Clicking that button will remove the offer from the pending list and return it to the main offer list.
Also, there is a lot of information in this thread that may help (2nd and 3rd posts):

It contains a list of a lot of different offer types and what you need to do to complete them.
Hope you enjoy the forum.
