Duplicate 1099-R data imported from my & my wife's accounts (Joint Return)

I imported 1099-R data from Fidelity from my retirement account & my wife's retirement account. Both accounts share the same JOINT brokerage account.  My account contains an IRA and a joint brokerage account record.  My spouses account has her IRA & the same joint brokerage account.  I found that TT thus downloaded duplicate info for the brokerage account.  At the import summary I CANNOT separate the brokerage account to delete one of them - I must delete both of the items on my account OR my wife's account.  At the dividend summary page, I also CANNOT delete any of the data (although it appears to have a "garbage can" symbol for each of the dividend records).  How can I delete the duplicate info?  Why does TT not at least recognize the potential duplicate downloads & flag them for additional review/removal on the initial import?
