User Problem

At the time of creation, if a sub-task inherits sprint values from its parent, then the Sprint ID recorded in the Issue sprint history table can have multiple sprint IDs concatenated as a single string. This makes it difficult to parse the sprint ID information from the Issue sprint history table record. 

Suggested Solutions

All sprint IDs should be displayed with one row for each sprint

Current Workarounds

The sprint information for a sub-task can be derived from that of its parent issue. Parent issues can be found by using the Jira Issue Field table with Field Type = 'parent'.
