I have two application links to two JIRA instances: my test JIRA (Localhost JIRA) and the company's JIRA. I created both application links, made the company's application link the primary one.

However, when I open the JIRA issue macro the wrong JIRA application link is selected, at least it seems so. However, when I excute a search, the search is triggered in the correct JIRA. I think the labels / names are not correctly set.
