Question about De'Longhi La Specialista Arte

It comes with a screw-on splashback, a spare filter for espressos, a pad for tamping the coffee, a small brush, a container for milk and a booster for small cups...... and a well-argued manual.

Good morning Mrs Leo.
I have ordered a replacement DeLonghi silk screen, the same as the original set that came with the purchase. Unfortunately the first thing I took out was the black plastic that divided the caffè feed when running out for 2-Expresso.
I saw on a YouTube video, there was a screen print that had no black plastic in the middle, but it looked like a funnel, so when the caffè flowed out it was for one cup.

After I took out the black plastic, I tried to repair it, because without the plastic, the silk screen has too many holes.
At the end at Amazon I saw a silk-screen that had no bottom, so the first original silk-screen that came with it, I cut the bottom with a Winckel cutter machine and now it only serves to make a ristretto. That's why I bought the original silkscreen parts again. I hope this serves. With fG, Cesare.
Regarding the Arte DeLonghi, I am very satisfied with it.

Everything is clearly visible in the photos in the description.
