Unable to rename plugin

I wanted to change the case of the plugin name, but I couldn’t.

If I change the plug-in “FOOBlender” to “FooBlender” in the middle, the plugin itself works correctly, but the job icon in the monitor disappears.

I was able to confirm that the icon is displayed correctly by setting the plugin to “FOOBlender” when creating the job file of the submission script.

Is there a way to rename the plugin or delete the plugin information once and for all?
