Key Value In Key Schedule Outputting as Double

Revit 2015
Dyanmo 1.2.1

When generating a Key Schedule from an Excel File to Archi-lab Key Schedule Node, the Key Value is coming out as a double instead of just integers. Am I missing a setting?

From Excel:

[0] 1
[1] Value1


[0] 2
[1] Value2

The resulting schedule shows

How can I fix that to just show as an integer?
