Can't select Sprint_id in mapping field of Jira when Improtting the test case

[Ngan Le]

I have imported a File test case with the Sprint column has the value as "396" ( Sprint id of project Xyz).

When going to Step mapping of Jira I don't see "Sprint'_Id" of Jira filed mapping 

If I select as Sprint. The Error will be displayed: 

"errors": [
{
"elementNumber": 0,
"errors": {
"otherErrors": [
"Number value expected as the Sprint id."
