Create issue : Test link integration with jira

I've integrated Testlink with Jira using below xml

<issuetracker>
    <username>xyz</username>
    <password>#123</password>
    <uribase>http://ift.tt/2lDxKmy;
    <uriapi>http://ift.tt/2li95I2;
    <uriview>http://ift.tt/2lDP5fd;
    <projectkey>KEY</projectkey>
    <issuetype>1</issuetype>
</issuetracker>

I am able to link existing jira issue in to test link.

But create issue window contains Version field which would not alow me to enter any value or not giving any suggestion as displayed in below image.

I've tried to create version in jira but it doesn't work.

So,

1. What value i should enter/configure for version field ?

2. What is use of 1 ? can we provide any other value?

3. How to link new field on create Issue window?
