FS22 Cows, Pigs, Straw, Manure

[Frostworg]

Hello I noticed the following while playing:

Farming Simulator 22 with Patch 1.2.0.2

no mods installed

Have on the French map, Haut-Beyleron, a farm with cowshed and a pigsty.

25 cows and 20 pigs with the right feed.

Now manure is produced in cowsheds and pigsty.

Then I thought that I could switch to stuff so I placed a stuff silo (not the extension).

As soon as the silo was placed, manure has already been spawned, without the straw in the barn.

I tried the same thing again with a new savegame again the same.

Is that so intentional the manure without straw in the stables Spawnt ?

Regards.
