They are cleared documents and they have cleared item also.
Check the offsetting account of this clearing document and check if you have cleared that item.
First you have to reverse that document. Follow the example:
[A] MIRO Post
D - EXPENSE
C - A/P
[B] F110 Post
D - A/P (clearing A/P MIRO posting)
C - Bank account(open item management)
[C] Clearing document
D - Bank account (clearing F110 offsetting post)
C - Bank account 2
You are trying to revers F110 posting [B], but the line item 2 of this document is cleared with document [C], so you have to reset and reverse or only reset first document [C].
