Summary

When searching for the issues in a particular Sprint (eg Sprint 1) using the Sprint name in the JQL (eg Sprint = "Sprint 1"), it will display other issues in other sprints that start with 1 (Sprint 10, Sprint 11, Sprint 12 etc)

Steps to Reproduce

1. Create a few Sprints up to 10 or more, so that the Sprint name will be 10 or more.
2. Go to the Issue Navigator.
3. Search using the JQL (replace project name and sprint name accordingly with your own.)

   project = "project name" AND Sprint = "sprint name 1"

Expected Results

The Issue navigator will ONLY return issues that are in "sprint name 1".

Actual Results

The Issue navigator will also return issues that are in "sprint name 10", "sprint name 11", "sprint name 12" and so on.

Workaround

Search for the issues using the Sprint ID instead of the Sprint Name for more accurate results.

You can refer to JIRA Software: How to search for a Sprint using JQL on how to retrieve the Sprint ID.
