Cursor jumps back to the last digit while deleting a digit

[mohsinabid]

I am using com.heidelpay.android.ui.IBANEditText and I have written 16 characters in the form of 4 groups. I clicked in the mid of that group and tried to delete a digit then cursor moves back to the last digit and deletes the last digit instead of the digit I wanted to delete.

Example: DE11 2233 4481 6677 8865

What I am doing: Removing 1 from "4481"

What is Happening: It deletes last digit "5" from DE11 2233 4481 6677 8865
