Essentially if the percentage is negative it does not render but if it’s positive it renders. It affects virtually all dashboards where the percentage value is negative so i suspect it is a server script issue.
I hope this can be fixed with the next beta release.

Unfortunately my history of reporting bugs doesn’t give me much hope of anyone attending to it because bugs I reported in the past were not fixed. I’ve ended up implementing workarounds for most of them so i don’t hold much hope for this one either.
