Multiple build strategies on GitHub Organization job not working as expected

[euan]

Hi

I have a github organization job running with both the
'ignore-committer-strategy-plugin' & 'basic-branch-build-strategies-plugin'
plugins installed. When selecting a build strategy to build tags, PRs &
ignore commits by a certain user commits by the user supposed to be ignored
are still being built. I can see in the log that the ignore committer
strategy plugin is running correctly but still the commit is being built.

Nov 09, 2018 10:10:16 AM INFO
au.com.versent.jenkins.plugins.ignoreCommitterStrategy.IgnoreCommitterStrategy
isAutomaticBuild
Ignored authors: [***@company.com]
Nov 09, 2018 10:10:16 AM INFO
au.com.versent.jenkins.plugins.ignoreCommitterStrategy.IgnoreCommitterStrategy
isAutomaticBuild
Changeset contains ignored author jenkins@ company.com
(adc2761857f7bf0fb62702f7ef0d5de7428321d0), and
allowBuildIfNotExcludedAuthor is false, therefore build is not required

When using these plugins independently they both work correctly so is this
expected? can multiple build strategies not be run together?
