Doxygen call graph is not correct even though the preprocessing is correct

Question

I have a function something like below. I run doxygen -d Preprocessor and check the preprocessed code and function2() is excluded. However, I still see the function2() in the call graph.

Configuration

Doxygen version: 1.9.1 (ef9b20ac7f8a8621fcfc299f8bd0b80422390f4b)

ENABLE_PREPROCESSING   = YES

MACRO_EXPANSION        = YES

EXPAND_ONLY_PREDEF     = NO

SEARCH_INCLUDES        = YES

CALL_GRAPH = YES
HAVE_DOT = YES
EXTRACT_ALL = YES
EXTRACT_PRIVATE = YES
EXTRACT_STATIC = YES
EXTRACT_ANON_NSPACES = YES

Function

void function(void)
{
    function1();

#ifdef filtered
    function2();
#endif
}
