Function parameters from stack, AVR8

[VladimirMeshcheriakov]

Hi! I am quite new to ghidra so this can be a very noob question.
I happen to have a variadic function in an avr binary that I am currently reversing, let me show you an example of where it is called:

So here we can see that the function take 3 parameters (of which 2 are 16 bit adresses and the last one is a bool)

There for I have tried to give the following signature

But when decompiling ghidra still does not seem to recognise the parameters...

What am I doing wrong here?
Thanks in advance !
