Importing OFX files shows strange window

[Paulo J. Matos]

Hi all,

Using Gnucash 2.2.9 here and once I import an ofx file I get asked to
match certain ids to certain gnucash accounts but then I get a window
with yellow transactions titled: Generic Import Transaction Matcher
with a heading List of downloaded transactions (sourch split shown).
It has a column A and R which I don't know what they are used for and
which I can select. What's this screen for and how do I use it?

Cheers,
