Converting Existing Boards into Roadmap wont bring in estimates.

[JD]

I am trying to bring in some project boards that already exist into Roadmap, but it isn't bringing the estimate with it. I have values in the "Estimate" field and in the "Story Point" field, just to try, but it doesn't show up in Roadmap. 

I also entered the estimate into Roadmap, but I don't see it show up in the issue. What field is it connecting between the issue and Roadmap estimate?  I am happy to adjust my screens/schemes/fields but am not sure what the connection is that I am missing. 

Any help would be appreciated.
