I have recently started playing with journals to keep a record of some of my results for large reports. Typically, I create a summary in Excel, particularly as I often need to touch up JMP graphs before using them in reports; I sent suggestions to JMP Support some time ago about how they can improve the user’s ability to set graphing parameters and make those settings more consistent across MP platforms. Anyway, I have noticed that JMP will loose the red triangles on outline items in the journal (see below).

In this journal, nearly all of the outline levels added by me have somehow lost their red triangles with the exception of the FDE outline item at the bottom—which I added just before taking the screenshot—the only outline items that have retained their triangles are those items added to the journal from platform reports.
How do I get the red triangles back or better, prevent them from disappearing in the first place?
