Importing sub-task are not importing multiple labels

[Brook marley]

When I attempt to to import sub-tasks with multiple labels, it imports successfully, but the labels are not imported.

 I also tried ,Labels 1,Labels 2,Labels 3 

and configuring them to map to Labels and this still did not import

File to import: 

Summary,Issue key,Issue id,Parent id,Issue Type,Status,Project key,Project name,Project type,Project lead,Project description,Project url,Priority,Resolution,Assignee,Reporter,Creator,Created,Updated,Last Viewed,Resolved,Votes,Labels,Labels,Labels,Description,Watchers,Work Ratio,Outward issue link (Cloners),Custom field (Acceptance Criteria),Custom field (Actual Effort),Custom field (Actual Testing Effort),Custom field (CS Training Topic),Custom field (Development),Custom field (Environment/Configuration),Custom field (Epic Link),Custom field (Estimated Effort),Custom field (Estimated Test Effort),Custom field (Feature Specification),Custom field (Issue color),Custom field (PS Knowledge Transfer),Custom field (PS Representative),Custom field (Rank),Custom field (Request Type),Custom field (Request participants),Custom field (Severity),Custom field (Sprint Priority),Custom field (Start date),Custom field (Story point estimate),Custom field (Technical Specification),Custom field (Test Scenarios),Custom field ([CHART] Date of First Response),Comment
