Release Date (internal) should should appear in correct location on Custom roadmap Merged

When using a Custom roadmap to display releases and show fields associated with a release, if showing dates, these dates need to appear in the bar in the correct place , as currently dates are just shown as text and their location bears no resemblance to the actual date on the roadmap timeline.

It is confusing when showing the roadamp to stakeholders, as they think there is an error.
