Negative Logistics Storage

[mcmase]

Anyone know what has to happen in order to register negative logistics network storage? I'm sure I'm missing something but idk what... basically I have a circuit, all it's doing is reading logi network contents from roboport, everything is coming back normal except I get a negative rocket fuel, fluctuating between 0 and -3. I would think because it's subtracting the 4 scheduled pickup every time 1 gets dropped in the buffer chest and goes to the depots? Any way to avoid this as it's causing issues in the circuit.

The negative requests are caused by materials being transported by robots, when picked up and placed again i would say from observations.

It is possible to use a decider combinator to filter all the positive signals to avoid this.

Ah thank you so much, yeah I was able to get that set up to remove that issue!

The exact moment the -3 will appear is the moment an idle robot gets a delivery task. It's reserving the items it will pick up, then starts flying to the chest to pick it up. It will always reserve its full carrying capacity, even if it is tasked to carry 1 item only.
This way items to transport are removed from the logistics network inventory not when they're actually picked up but already when they're reserved to be picked up. The -3 are "given back" the moment the robot actually picks up the one item. If more items were added while the robot was flying to the pickup location, the robot picks up more - up to 4.
