Every time I install the plugin and try to create a new slave I get the following error in the slave configure logs.
Stack trace

javax.servlet.ServletException: org.apache.commons.jelly.JellyTagException: jar:file:/var/jenkins_home/war/WEB-INF/lib/jenkins-core-2.19.4.jar!/hudson/model/Computer/configure.jelly:43:71: <st:include> No page found 'configure-entries.jelly' for class com.cloudbees.jenkins.plugins.amazonecs.ECSSlave

This is a new system so I have the luxury of completely redoing the installation if required for troubleshooting assistance.
