LineStyle does not show "(0)ByLevel" in its combobox with Filter= All

MS CE- Version 10.16.00.80 Windows x64 , Using RealDWG 2021

Is this behaviour correct?

In the Attributes group of the ribbon, if you drop down the list (combobox LineStyles) and Filter= All, it does not show "(0)ByLevel"...

With Filter= Built-in Styles, it shows it.
