Data not updating on Contact tab when updated by Zoho Recruit API

Hi,
I have a critical question. I am updating a Candidate / Contact information by candidateid using zoho recruit api. Here is the sample api call:
<row no="1">
<FL val="Id">384474000005042923</FL>
<FL val="First Name">xxxxxxxxxx</FL>
<FL val="Last Name">xxxxxxxxxx</FL>
<FL val="Email">xxxxxxxxxxxxx</FL>
<FL val="Mobile">xxxxxxxxxx</FL><FL val="Phone">xxxxxxxxxxxx</FL>
<FL val="Description">https://www.facebook.com/</FL>
</row>
</Candidates>

I want to change his phone and mobile number. The api returns success. Sample API response is:
<?xml version="1.0" encoding="UTF-8" ?>
<response uri="/recruit/private/xml/Candidates/updateRecords">
    <result>
        <row no="1">
            <success>
                <code>2001</code>
                <details>
                    <FL val="Id">yyyyyyyyyyyyyyy</FL>
                    <FL val="Created Time">2019-06-14 13:58:53</FL>
                    <FL val="Modified Time">2019-09-21 10:12:42</FL>
                    <FL val="Created By">
                        <![CDATA[yyyyyyyyyyyyyyy]]>
                    </FL>
                    <FL val="Modified By">
                        <![CDATA[yyyyyyyyyyy]]>
                    </FL>
                </details>
            </success>
        </row>
    </result>
</response>

But question is: when I search this contact on "Contact" tab of CRM page, I cant find this contact information updated. Contact information remains same as previous. Can you please advise me how to fix this ?
