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: [jen...@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?
