Why does not bamboo labels show up API responses

[Jonas Andersson]

We have the build plans add a label named ‘release’ where appropriate, so that we can identify these builds for monthly reporting needs.

See the url’s below

https://bamboo.OUR.FQDN.GOES.HERE/browse/PB-PITBULLDEV405-4 - This build summary has the labels “deploy” “pitbull” and “release” attached.

https://bamboo.OUR.FQDN.GOES.HERE/browse/label/ (this shows us this is true)

and this

1. https://bamboo.OUR.FQDN.GOES.HERE/browse/label/release

as does this

2. https://bamboo.OUR.FQDN.GOES.HERE/browse/label/deploy

and lastly this

3. https://bamboo.OUR.FQDN.GOES.HERE/browse/label/pitbull

Now I should be able to (according to the documentation) - query the Bamboo Rest api, and return a list of Builds, by label name

Like so: https://bamboo.OUR.FQDN.GOES.HERE/rest/api/latest/result.json?label=release&max-results=999

but all I get is

Yet the results are not what we expect, according to the url in point 1, I have 4 builds with the label ‘Release’

This works, searching for “rdi”

https://bamboo.OUR.FQDN.GOES.HERE/rest/api/latest/result.json?label=rdi&max-results=999

Am i hitting a reserved word, or what could cause this behavior?
