When using the mapping ${Key} in a &{for issues} iteration, if we use a JQL clause in the template, the iteration of the JQL clause is stopped after exporting one element.

Steps to reproduce:

Use the following template, to export a list of Stories and Test Plans grouped by Component: Example.docx

Workaround:

If we replace this mapping with another, like Summary, or mention the ${JQLIssues[i].Key} mapping inside the JQL iteration, then the template works as respected: Example2.docx
