Selecting ‘Issues linked to current issues' as a scope for an advanced issue panel creates a detailed issue table as an alternative to the default ‘Linked Issues’ panel.
Apart from the usual configuration of displayed data such panels have the option to show link type between the connected issues.
To enable the display of the link type:
Go to the panel configuration page.
In ‘Data logic’ check that the scope is set to ‘Issue linked to current issues’
Switch to a ‘Display style’ tab.
Mark the checkbox ‘Show Link Direction Name’.
