How to display the Gender value in outlook when setting it via GraphAPI using singleValueExtendedProperties

Question

I have a requirement where I want to synchronize value of Gender(including other) of contacts from my application towards Outlook. I am setting up the Gender value(property tag - String 0x3A4D) using singleValueExtendedProperties, and am able to retrieve Gender value it after creating the contact using expand on singleValueExtendedProperties

eg -

https://graph.microsoft.com/v1.0/me/contacts/{contact-Id}$expand=singleValueExtendedProperties($filter=id%20eq%20'String%200x3A4D')

response -

"singleValueExtendedProperties": [
        {
            "id": "String 0x3a4d",
            "value": "Male"
        }
    ]

**pasted only the desired section here

Unfortunately the value of gender in Outlook stays to default "unspecified" for the contact.

Any ideas around how to display the Gender value as passed on?
