Two-Dimensional Filter Statistic Gadget showing wrong links

Steps to reproduce the problem:

1. Add a project with some issue types (bug, task, sub-task, release)
2. Project needs at approx 10 components.
3. For one particular issue type (in our example lets take the "bug"),
4. Hide the component/s in the field configuration of that particular issue type.
5. Add a filter that is searching for your project and for all issue types
6. create a two-dimensional filter statistics gadget that is using this filter:
   • x-axis: issue type
   • y-axis: components
   • Number of Results: 1
7. See two_dimensional_gadgets_links.png and two_dimensional_gadgets_links_2.png
8. It seem showing the following stack trace in JIRA log:

The bottom of the result the link "show more" is not where it should be and the name of the link is "show less" instead.
