Several times now, I have seen the instance where a single job is taking up all of the locks with the specified label while the quantity is set to 1. The pipeline code is as follows:

{{
// Pipeline Details
def pipelineName = "pr-pipeline"
def lockLabel = "pr-pipeline"
def lockQuantity = 1

// Pipeline
lock(label: lockLabel, quantity: lockQuantity)

The attached picture is a single job taking up all of the resources with the label. I'm not sure how this situation arises,
