[JENKINS-31042] Not running the job on all slaves in Label parameter

I have assigned 5 slaves with the same label name (EX: dev_sev). I want to run a job concurrently on all the 5 slaves using the label parameter. Within my job, I have created parameterized Label and set label value to (dev_sev). I have also selected the following options, "Run on all nodes matching the label", "Run regardless of result", Node eligibility: All nodes", and "Execute concurrent builds if necessary".

When I execute the build, the label shows up and I can see all the 5 slaves show nodes, but the job is running on one of the nodes only. How do I resolve this issue with label param? I don't want to use a node parameter.

• environment: Running 1.625.1 on LInux

Reproduce the issue using Jenkins 1.625.1, five agents sharing the dev_sev label, and the listed Label parameter options. Start by inspecting the nodelabelparameter-plugin behavior for running on all matching nodes; done means one build executes concurrently across all five matching agents.
