Short description of error
If you create a preset and you name it the same way as the built-in presets, they can no longer be deleted and Blender recognizes them as defaults.
Exact steps for others to reproduce the error
Go to any tab in the properties with customizable presets> click on the Presets icon> name the preset the same as the Blender built-in ones and add it> click on the minus icon to remove the preset.
