From that print screen the buttons look good.
You certainly do have some issues with the mode change app. You should have 5 things to setup when going into the app as show in in my previous screenshot. If you don’t have that then just delete it and download it again from the repo.
That is what the info looks like in my IDE for my repo. Just to clarify
Owner = Mavrrick
Name = SmartThings-by-Mavrrick
Branch = master
That repo is open to the public so you should be able to get the apps right from there. If you can get that working we can ensure there are no issues with getting the apps into yor IDE.
In your IDE you should see something like this that will list the parent and child apps. Notice only the ADT Tools app is published.
Once all of the apps are loaded you should go to the Automations tab in the Smartthings Classic app. Click on the Smartapps tabs in the upper right. Scroll down all the way to the bottom and click on “+ Add Smart App”. From there Select “+ My Apps” at the bottom. Most Likely you will see “ADT Tools” near the top of the list of smartapps. Click on ADT Toolsand you will be presented with a list of child apps. From their select the option for “Allows Changing Alarm Mode from Smartapps” option and you should see the ADT Mode change app pop up and it’s setup options. Configure it as we have discussed earlier.
