Issue generating Discrete Laminates for Composite panels

[z__4yn]

I'm attempting to perform detailed sizing on composite panels and am able to generate effective laminates (7 candidates are produced). If I try to generate discrete laminates for the components I get an error message stating Error #3316, Laminates must be numbered 20000 through 29999. I've tried reducing the number of discrete lamiates to generate however the error still appears. Has anyone come across a similar error or does anyone know how to get around the issue. The issue is causing negative margins of safety to exist for about 20% of the components within the assembly
