I've an issue with Craft Data images when I wan't to put them in my Symbols.
When I want to put an image in my Grey Rectangle (img 1 & 2), Craft Data doesn't show me the window which permites to choose a layer.
When I want to do the same in the images 3 & 4, Craft Data shows me the window, but my Grey Rectangle isn't here, there just are my 3 pictograms and I don't want to apply an image in them.
Can you tell me the difference between my pictograms and my rectangle ? Why my pictograms can receive images, while my rectangle can't ?
Thank you for your help, and sorry for my approximative english...
