Unable to generate artwork because of polarity issue & unable to delete layer.

Hello,

I am working with a 4 layer board and trying to generate the gerber files required for fab. I am having issues with generating the artwork for my GND layer. It gives me the following error:

"ERROR: aborting film - Layer polarity of layer ETCH/L2_GND does not
match film polarity of Positive. DRC may be unreliable."

I tried various ways to fix that first, but it didn't work. Now I am trying to delete that layer and create a new one but it also doesn't let me delete that saying the following, even though I deleted the copper pour from that layer and there are no elements left on that layer.

"Layer being deleted: ETCH/L2_GND

(-5802.437 -1990.874) TEXT LINE: L2 Gnd
(-5802.437 -1990.874) TEXT: L2 Gnd
(1220.232 2564.340) DYNAMIC SHAPE: Gnd, Boundary/L2_Gnd
(1008.084 2352.192) SHAPE(auto-generated): Gnd, Etch/L2_Gnd "

Can anybody please lend me some help or direct me to the solution, I am very lost at this point. Any help would be really appreciated!

Go to Setup>Cross Section, expand the Physical settings and uncheck all of the Negative Artwork boxes, OK that and update the Shapes before generating artwork.
