Style Customization - Mapmint

[mlfiras]

Hello again, I tried to customize my points in mapmint using the "Graduated Symbol" option, it works well unless I have a "null" value. in fact Mapmint consider the "null" value as 0.
For example, in my case I have a table in postgresql that contains values for the state of my points.

The next image shows the expression settings that I wrote:
( ( [current_state] = -1.0 ) AND ( [forecasted_state]=0) )

Normally, Mapmint should display only the point that have 0 in "forecasted_state", not both; but as you can see it's showing two points.

My question: is there any way to display points with null values using the expression settings ?

Thank you in advance !

I forgot to mention another error:
after customizing my points into classes with images in the Manager

I discovered in the Preview that the points are just transparent circles.

But, if I set my layer to Raster in (Publisher -> Layers -> Overlay Layers), the icons appear normally:

Do you have any idea, what's causing this ?
