Bug when editing/loading Roadmap Planner macro in Confluence page

[Dan McGrath]

Hi, I am editing an existing roadmap planner on a confluence page, but when I update a bar's visible banner text, the roadmap macro completely disappears and turns into some kind of image file instead... almost like some kind of rendering issue.

I had to restore to the previous version, but editing that also causes the same problem once again.

Does anybody know what is happening? Maybe some kind of length, certain characters are not accepted such as:   (){}&+

I have the same problem.  I tried using IE and Microsoft Edge, neither works too.

I had a similar problem occur again yesterday when I added comments to a specific bar - the chart turned into an image file of just the comments I had added. Restoring the previous version of the page fixed it - and I didn't re-add the comments.
