Problem description

Navigate back button is disabled when we skip two repeat groups.
We can use this form:
testx.xml.txt

I also noticed that repeat groups must contain other groups inside, If we have simple repeat groups like here:
testx2.xml.txt everything works well.

Steps to reproduce the problem

Don't add the first group.
Don't add the second group.

Expected behavior

Navigate back button is disabled.
