I think you are using Android version of the app. aren't you?
I already wrote to Roco that In the android version only reporteraddress 1-20 can be set for loconet responsemodule (uhlenbrock or Blucker), while iOS version allows reporteraddresss 1-2048 (see picture). They reply me that is a know bug, and should be solved in the next release.
The old android app has no such limit, you can select the Uhlenbrock 63320 and set address 1 to 9999.
