Problem with new companies... but no cargo

[Miritellane]

Hello
I have just created a new city containing 2 companies including one already existing elsewhere.
I created my city as usual, and it is recognized on the map...
I created my 2 companies as usual, and they are recognized and seen on the map, and on the freight manager.... But
I have no freight proposal for these 2 companies....
I checked all the files. If they’re in order...
I have files in and out, and companies are well declared in this city (company/editor...)
I tested different routes, I connected businesses with prefabs, like everywhere else on my map,
I tried to change the prefabs, and even the company name,
the area of the city covers well the 2 companies...
I checked the continuity of the roads that pass through this village, it’s OK
BUT I still don’t have any cargo...
and I don’t know where to look....
the editor.log doesn’t give me any relevant info, nor the game.log

If you have an idea that might help me solve this problem, I’m happy to...
I don’t know what to do anymore..
Thank you in advance...
