Layer options is gone specially in children Layers made with earlier version of Illustrator

[hsawires2]

I used to double-click over any layer to activate the layer option dialogue box. 

recently after updating to Illustrator 2021 the layers option is gone especially with files I have made with earlier Illustrator Version and on children layers only.

all layers I have made in an earlier version of Illustrator have colors that I couldn't change in the newer version of Illustrator.

This is what I got when double-click over any layer to change its color for example.

It looks like you are double-clicking a group item in the Layers palette, not a layer or sub layer item (technically speaking).

In that case the behaviour is just normal.

you are right.

but the question is, how could I assign a color to a group/objects in a layer in an earlier Illustrator version?!

it is very weird for me I usually double click and get options to any object or group in a specific layer.

besides that .. when I assign a color in a layer it should assign either to all its children and this I not happening in my case. the group/object has its own assigned color I assigned previously in old Illustrator version.

I do not remember any version of Illustrator that allowed assigning a colour to groups in the Layers palette. It used to be only possible with main layers or sub layers.

Which version of Illustrator do you think had that capability?
