Roadmap Planner Bar and mark dates getting crashed upon insert/publish

[Brad Lackey]

I've just created my first Roadmap Planner, and for some reason the bars and markers around a certain date at the end of my calendar get crashed in/pulled forward upon insert and publish. I can add a bar well beyond this timeperiod and it doesn't move. I've tried a brand new lane, removed the marker, all still occurs. I can't seem to zero in on what the root cause might be.
