As you can see from 1 & 2 in the first screenshot below, there is a Bible entry for 1 Esdras. However, as shown at 3 in the second screen shot, the Bible entry for 1 Esdras is not offered as an option. Yes, I know that the data still has a lot of cleanup/conversion to be done and that there is a database of equivalencies hidden in the background, but it is still confusing to be able to add a precise tag as a community tag and then not be able to access that precise tag in Factbook.
