Formula repeats only once

Hi All,
I'll appriciate your help by getting in table 2 values only ones (i'm doing v-lookup to sumif from table 1), per attached (without the yellow items).
Thanks for your help,

Why are A & B in table 2 twice? Just remove them?

If you want unique list in G

in G3

=IFERROR(INDEX($A$2:$A$8,MATCH(0,INDEX(COUNTIF($G$2:G2,$A$2:$A$8),0,0),0)),"")

copy down

in H3

=IFERROR(VLOOKUP(G3,A:C,3,0),"")

Thanks a lot!
