I’m working with Jenkins coverage plugin to evaluate pull request coverage, my plugin is defined

                discoverGitReferenceBuild(targetBranch: 'develop', scm: 'our_scm')
                script {
                    if (env.CHANGE_TARGET != null && env.CHANGE_TARGET == 'develop'){
                        recordCoverage(tools: [[parser: 'JACOCO']],
                                       id: 'jacoco', name: 'JaCoCo Coverage',
                                       sourceCodeRetention: 'LAST_BUILD',
                                       scm : 'our_scm',
                                       sourceDirectories: [[path: 'glob:**/src/main/java']],
                                       qualityGates: [[threshold: 75.0, metric: 'LINE', baseline: 'MODIFIED_LINES']])
                    }

For some reason in some cases we get
