Inconsistent Function signature between rizin and rz-ghidra

[CHr15W3]

Hi,
Sorry if this is a noob question, it somewhat resembles #119, but for functions for which rizin knows the correct signature. I built a simple example binary, one function has the following signature when using afs:

[0x00001229]> afs
void check_password(char *password);

Password is also a variable in rdi:

[0x00001229]> afvr
var char *password @ rdi

however, the signature in rz-ghidra differs:

[0x00001229]> pdg
void check_password(char *param_1)
{
    int32_t iVar1;
    char *password;

Is this a skill issue (i.e. do I have to define the argument differently) or a limitation of the interoperability between rizin and the ghidra decompiler?
