Ziti mobile edge android tunnel configuration edit not working

Hello, when I try to edit the tunnel configuration on the android mobile edge app by navigating to main menu -> advanced -> tunnel configuration, i see few variables that I would like to change but i cannot. I see only the back and save button but the fields are not editable and there is no button to edit them. I am on version 0.12.1, but I tried previous versions but those didn't work either. Please fix this issue, as it makes the app unusable for me. Btw, the tunnel configuration can be changed in both the windows client app and the ios client app without any problem, only the android app has this issue.

the values on this screen are actually not used at all

actual settings of Android tunnel interface are 100.64.0.0/10, dns: 100.64.0.2

Why is it not working for you?

In the end i figured out that the issue was with with the mobile phone. Other Androids work fine. But still, why is this option there if it isn't used? And why is it editable in the windows and ios client apps?
