This needs one Helper Column & combination of INDEX and MATCH, wrapped with IFERROR:
How it works:
Formula in cell P41:
=IF(ISNA(VLOOKUP(M41,$N$41:$N$423,1,FALSE)),"Yes","")An array (CSE) formula in cell O41:
{=IFERROR(INDEX($M$41:$M$47, SMALL(IF(COUNTIF($P$41, $P$41:$P$47)*COUNTIF($P$41:$P$47,"<>"), ROW($M$41:$N$47)-MIN(ROW($M$41:$N$47))+1), ROW(A1)), COLUMN(A1)),"")}
N.B.
Finish an array formula with Ctrl+Shift+Enter & fill down.
For neatness later on you may hide Helper Column.
List in column O will change, as soon you add or even delete value in column N.
Adjust cell references in the formula as needed.

You could use:
=UNIQUE(IF(ISERROR(VLOOKUP(UNIQUE(B1:B20,0,TRUE),UNIQUE(A1:A20,0,TRUE),1,FALSE)),UNIQUE(B1:B20,0,TRUE),""),0,1)
instead.
