Dismantling in the Buffer

Hello Community,
I want to ask your advice on the proper way of Assembly dismantlement at the Buffer and statistics presentation.

The right process sequence should be following:

  1. The KLT red box delivers product block to the double level station.
  2. The Product block is removed from the KLT box at the bottom level (hypothetically by human - buffer process time will be adjusted) and the KLT placed on the top level for removal.
  3. Statistics must show exact number of products on the bottom level.

How can the pre-entry process node No.1 be eliminated (applied only for managing the material flow purpose), because the statistics does not count the pre-entry quantity on the bottom level.
If there are 3 products at the bottom level, so the statistics single chart shall show 3 products at that time.
A simpler solution is appreciated ASAP.
The case file is attached.
