formula to determine value appears more than once based on crteria

I have for values in Col D and Branch + "PL" or Branch + "statement" in Col B eg BR1 PL or BR1 Statement

I need to set up a formula so that where the value is the same and the branch in Col B contains "PL" and "Statement" for the same value then display "Delete" , otherwise blank


I have shown what the result should look like in Col F by manually inserting Delete


your assistance in this regard is most appreciated

=IF(COUNTIFS($B$2:$B$6,SUBSTITUTE(B2,"PL","Statement"),$D$2:$D$6,D2),"Delete","")

Note:

It works for 85.05 vs 85.05

It does not work for 85.05 vs (40 and 45.05 or 30 and 55.05,...) (If this is probably the actual case)
