Jaeger Tracing not working with yaml-cpp version 0.6.x - yaml-cpp

Question

I am trying to instrument my program with jaeger-tracing (c++).
I was able to view my traces when I compliled the program with yaml-cpp version 0.5.3, but when I changed my yaml-cpp version to 0.6.x, I am unable to view my traces.
Dont know why its happening.
JaegerProgram Source code;
#include <iostream>
#include<memory>
#include <yaml-cpp/yaml.h>
#include<jaegertracing/Tracer.h>
#include<chrono>
using namespace std;
// using namespace literals::chrono_literals;
void init(const char *FilePath)
{
auto yaml = YAML::LoadFile(FilePath);
auto config = jaegertracing::Config::parse(yaml);
auto tracer=jaegertracing::Tracer::make(
"example-service-2",
config,
jaegertracing::logging::consoleLogger()
);
opentracing::Tracer::InitGlobal(
static_pointer_cast<opentracing::Tracer>(tracer)
);
}
void ChildSpan(const unique_ptr<opentracing::Span>& parentSpan){
this_thread::sleep_for(chrono::milliseconds(2));
auto childSpan = opentracing::Tracer::Global()->StartSpan("Span2",{opentracing::ChildOf(&parentSpan->context())});
}
void FollowsSpan(const unique_ptr<opentracing::Span>& followFromspan){
this_thread::sleep_for(chrono::milliseconds(3));
auto followSpan = opentracing::Tracer::Global()->StartSpan("Span3",{opentracing::FollowsFrom(&followFromspan->context())});
}
void ParentSpan(){
auto span = opentracing::Tracer::Global()->StartSpan("Span1");
ChildSpan(span);
FollowsSpan(span);
this_thread::sleep_for(chrono::milliseconds(4));
}
int main()
{
init("./config.yaml");
ParentSpan();
cout<<"Hello World"<<endl;
opentracing::Tracer::Global()->Close();
return 0;
}
compiling command - g++ -std=c++1z test.cpp -L /usr/local/lib/libyaml-cpp.a -ljaegertracing -lyaml-cpp
Yaml file
disabled: false
reporter:
logSpans: true
sampler:
type: const
param: 1
OS : ubuntu 18.04
jaegerTracing : master branch version
UPDATE
after little digging I found some fact, When I parse the above mention config file try to print the result I get the same value as written in config file, but when I parse same file using yaml-cpp-0.6.x the sampler.type is showing 'remote' and sampler.param to be '0.001' and when I manually change this change these values to be same as in config.yaml it has started showing traces. The error is present in parsing the yaml file as I could clearly see different values is loaded as configuration.
