Double entries from Bills Inbox and manually entered expenses

Hi, I have just gone through my Bills Inbox and uploaded the necessary statements from my rental agents and also any repairs invoices. By doing this, I have duplicated some invoices and therefore claimed expenses twice. There doesn't seem to be an option to delete the ones that I previously entered manually. How do I delete the ones that I have recorded manually? I need to do this so that I am not claiming expenses twice. Also today I e-mailed through 3 statements from my rental agent to my Bills Inbox, and they have not shown up. Only those that I have attached and allocated (and sadly managed to claim expenses twice in the process!) are showing. This is all new to me. Hope someone can help.
