Struct variables are generated inconsistently with Embedded Coder

I am trying to generate a C++ code for my Simulink model. Everything works fine, but the problem I have is that the struct name that is generated is not consistent, and I am not sure what the problem is, although I have not changed anything in the Embedded Coder Configurations.

For example:

Before the struct was generated as follows:

struct ExtY_moduleName_T

Now it's just:

struct ExtY

Or

// Parameters (default storage)
struct P_moduleName_T

Now it's just:

// Parameters (default storage)
struct P

How can I keep this consistent, what causes the _moduleName identifier to be removed ? I checked under Settings -> Code Generation -> Identifiers and this is what I got:

On the left are the expected values and on the right are the new values (without _moduleName), why did it change ?

I'm using Matlab R2023b.

That can be explained by the "$N$R$M_T" on the left and "$N$M" on the right for "Global types". "$R" means root model name. "_T" is explicit suffix.

What do you mean by "expected" and "new". They are two model configurations. They are apparently different or has been changed for naming rules for "Global types".

This means that the configurations change by themselves for some reason. Last week they were the same as those shown on the left.

Left side seems to be the default for ert.tlc.
