Marks not showing in combo chart legend

[Brites]

I am building the following combo chart, but i cannot find how to add the mark's legends along the lines. 

As you can see, the legend only name the lines, not the dots.

Can you give some more details?

What version of Qlik Sense are you using?

Is this the standard combo chart?

How have you added the lines, are they a primary or alternate measure?
