A fix for the issue is scheduled to be included in the Aria Automation 8.15 release
To workaround the issue you can perform either of the options described below:
1. Do not set the array input value to read-only and they will display correctly as integer.
Or
2. Use a constant and hard code the values on the form, it can be read only and display correctly as integer
The array input type integer displays as a decimal if set to read-only.
