Layer Filters do not work

Stumbled on another one:

I am used to work with a lot of layers. In order to organise my workflow I use layer- filters.
Most of the time I use group- filters in AutoCad which makes it possible to drag and drop any layers into.
I understand that Bricscad is lacking those, is that right?

I Bricscad 16 I tried to make a new layer filter based on a layers name. My layers always start with '_' in order to make them appear on top.
When I define the filter by typing '_*' in the field 'name', all layers appear in the list, which should not happen, right?

Anyone else hang this issue?
Any suggestions?
Thanks in advance.
