Using this parameterized blueprint, setting the item to a requester chest will causes flickering behavior. setting it other crafting items is fine:

Not a bug. There was a behavior change around assembling machine's set recipe between 2.0 and 2.1 where set recipe no longer does magic self subtract to ignore values assembler is sending, and your assembler also has "read ingredients" enabled which provides signals that are interfering with "set recipe". You will have to update your blueprint to use the checkboxes near the Input line and Output line to select which wires will get ingredients content and which wires will be used to set recipe,
