Version Report Does not 100% when all Stories are Done

Version Report graph does not show 100% completion when all Story Points are Done. For example, from the default generated Sample Scrum Project:

• The version has 8 out of 8 story points complete.

The Graph accurate depicts the Story Point axis on the left with 8 Story Points complete, but the Percentage is incorrect. The Percent axis on the right shows 90%, where 100% would be expected.

I've run multiple tests with different versions and projects and the results are the same, where the percentage does not reach 100%.

Steps to reproduce:

• Generate the Sample Scrum Board for JIRA Agile
• Navigate to Version Reports
• Check the different versions and observe the graphs
• Compare to the list of issues, notice that all stories are complete, but the graph never reaches 100%
