Keychain Access import results in two items for each login item from 1Password

I exported my 1Password login items to .csv and imported that into my Mac Passwords. Keychain Access shows two entries for each login item:

  1. Web form password, which appears to contain all that’s needed.
  2. Password Manager Metadata, which duplicates the info in item 1.

However, web form password items are in the com.appl.cfnetwork “access group” and Password Manager Metadata items are in the “access group.”

Do I need to keep both 1 and 2 in Keychain Access, or is the Password Manager Metadata a vestige of the import process I can delete?

I could find no reference to these Keychain Access item “kinds” with web searching.
