I use JobDSL with seeders to create jobs. Jobs are created correctly and no issues are presented in the logs. When I attempt to modify the jobs manually, I first get an Error with a logging hash. Eventually a second attempt succeeds but the Jenkins logs show the following error:

Error while serving https://JENKINS_URL/job/FOLDER_JOB/job/JOB_NAME/configSubmit java.lang.IllegalArgumentException: The frontend sent an unexpected list of classes (["pl.damianszczepanik.jenkins.buildhistorymanager.BuildHistoryManager","hudson.tasks.LogRotator"]) rather than an expected single class. See https://www.jenkins.io/doc/developer/views/table-to-div-migration/ for more information. at org.kohsuke.stapler.RequestImpl$TypePair.convertJSON(RequestImpl.java:723) Caused: java.lang.IllegalArgumentException: Failed to instantiate class jenkins.model.BuildDiscarder from {"stapler-class":["pl.damianszczepanik.jenkins.buildhistorymanager.BuildHistoryManager","hudson.tasks.LogRotator"],"$class":["pl.damianszczepanik.jenkins.buildhistorymanager.BuildHistoryManager","hudson.tasks.LogRotator"],"daysToKeepStr":"","numToKeepStr":"10","artifactDaysToKeepStr":"","artifactNumToKeepStr":""}

Once the error shows up, the Discard Old Builds is no longer checked and if I were to check it and choose Log Rotator, I won’t see the days/builds fields. 

A Jenkins restart will bring back the log rotator options for daysToKeep and buildsToKeep.

This behavior occurs in an updated Jenkins environment. Production does not experience this behavior.
