Why are "Argument" parameters not exported in FMU 2.0 in MATLAB R2024b?

I have created a Simulink model in MATLAB R2024b, and I am exporting it as a FMU 2.0.
In the FMU Builder, all the parameters for the model have got the "Argument" attribute enabled.
However, when I generate the FMU, I get the following message:

Warning:Non-tunable parameters are not exported
...
Make the parameter tunable in order to export it.
Is there a way to correctly export these parameters?

Some parameters may not be exported as FMU arguments if their value does not impact the simulation. This may happen if for example "Unit Delay" blocks are included in the model that override the value that is set by a parameter.

This is expected behaviour when exporting the FMU.

To correctly export these parameters, they can be connected to an "Outport" or a terminator block.
