Ok, sorry for being unclear:
I didn't have this issue with 0.8.6a a few days ago, when I first used this filter; now with 0.8.6c I have this issue:
I have a big storage (the production one) where I want to only allow yellow trucks now, and disallow amphibious ones.
I have a smaller storage, near my bridge construction site, where I want amphibious trucks to go get the materials: they don't, they go to the big one, farther and not allowed to them in theory.
The picture is where I disallowed amphibious trucks, at least it was my objective.
Thanks
Edit: more tests: I removed the filter on the small storage saying that only amphibious trucks could take from it (deposit is blocked for everyone) it worked better: like the filter allowing only is doing the opposite. I'm testing now if the filter set on the picture above blocks yellow trucks from taking materials
