There's something wonky with parameterized blueprints. If I create one with a requester station (just selecting an item and setting the request to stack size × number of stacks), then after placing the blueprint the station immediately thinks the request is already satisfied. I have to open the combinator, reselect the item, and click Apply before it starts requesting anything.

can you paste your parameters here and a screenshot.

My recommendation:
Help > Pause RLD

1. make a requester station with the requester unchecked, and add your preferred item in and set the stack size. This way when you place it, it automatically is disabled.
2. blueprint it, and choose parameter 0 for the item, then under stack size set it to p0_s*400 if for example you want your deposit or iron chests want to hold 400 stacks total.
3. make sure all your chests are wired to the RLD combinator and the station.

After testing blueprinting, un-pause the dispatcher

I've move the conversation here so you can paste pictures:
