I tried to delete an environment variable in the System Configuration. But when I click on both Apply and Save, no change ever happens.
The variable I want to delete is a variable that I edited to do some tests with the "Poll Mailbox Trigger" plugin.
Actually, no element that I modify in System Configuration seems to have an effect, can this be some error of the Jenkins version? I currently have the version 2.289.2.
I will show a step to step on how I try to delete the configuration:
Hope it is clear and someone can help me, thanks.
