Pipe character causes Field Groups to disappear in Live Template
If the pipe character is used in a Field Group, the Field Group and its text does not render properly when the page is used as a Live Template.
Field group text disappears when the page is published.
An issue in Confluence is causing unexpected behaviors when the pipe symbol "|" is used within Scaffolding Field Groups. This has been reported to Atlassian.
Currently there is no workaround for this issue, other than to avoid using the pipe symbol "|" in Scaffolding Field Groups.
This is currently listed as a bug by Atlassian. No timeline has been provided for fixing this bug.
