A 2-pack sticker on singles is a new child
Two singles sit in a bag with a “2 pack” sticker. The live ASIN is still the single. If you change that title to 2-pack, every remaining single is a defect. The Transformation Kit is the check before you receive that bag: a new pad for the 2-pack, and the single listing left alone.

Open the bag you will actually ship
Write type, size or count, material, and what is in the box from that 2-pack. Photo of the pad next to the bag. Count is two. The single carton still has its own pad. Do not “update the parent.” A sticker does not merge two offers. If you still have singles in FBA, they need the single listing to stay true.
Create the 2-pack child, then receive against it
Title and first bullet from the 2-pack pad. Save the new child. Run free optimize only if that English still reads like a single. Receive the bag on the new child. Leave the single title and inbound on the single ASIN. A shared SKU here is how the warehouse mixes them.
A sticker is not a title edit
