Can't hide the factory fx chain presets

Hi,

Ever since updating to v13, I can no longer hide the factory fx chain presets. In v12, I was able to go into the mediabay and uncheck the Factory Content/fx chain presets folder from the file browser. This worked perfectly and only my user presets would show. With v13, this folder is already unchecked (see picture) and there is no way to check this box.
Is there a new way to hide these presets?

Thank you,

Peter
