Unresolved Storage Class in Code Mappings - C

Hi,

When generating C code for and Embedded Target, i noted that i cannot assign "Exported Global" Storage Class to my Signals/State.

All I see now is "Unresolved" Storage Class and I can only choose "Auto" Storage Class. This is very strange, as it happened overnight: previously, i've selected and correctly generated code with "Exported Global" on the same simulink model on the same R2020b Matlab version.

Can someone help?

Thank you!

Have almost the same problem. Anyone found out why this happens ?
