after updateing the build-pipeline to 1.3.4.1. And jenkins to 1.520 all my pipline configuration are gone. Any new configuration have no affect. On the pipline page there is this error message:

makeStaplerProxy('/$stapler/bound/d3fbd014-3909-4a15-9246-39f5fd687e2e','95e5bbc943cc4cda47bb2806d8975deb',['triggerManualBuild','retryBuild','rerunBuild']), Handlebars.compile(buildCardTemplateSource), Handlebars.compile(projectCardTemplateSource), 3000);
