This https://academy.mendix.com/link/paths/83/Build-an-App-in-Mendix-Studio is what you are trying to follow, right?
Maybe you are confused between Mendix Studio, which is the webversion used in a browser, and Mendix Studio Pro, which is the desktop version that you download from here https://marketplace.mendix.com/link/studiopro/.
If you have some other problem then please let us know exactly at which step in the training your run into a problem. Add some screenshots too.
So from your screenshots, it looks like Tim Steenbergen is right – you are using Mendix Studio Pro, which is an entirely different product than Mendix Studio. To follow the Mendix Studio learning path, you don't have to install anything, you can simply use Mendix Studio in your browser. Be sure to carefully follow the first steps in the learning path.
Now I erased the SLA Task App and start again.
I think there is a incredible different and not really good things. For example I am also following other courses too. Main problem is about version that which you are using. I had another education to this problem. I think this is really critic and cronik problem. For example you are watchin 2 version before with eduction videos and than you are trying to last and recent version practises. Then pufff not working. Incredible. My computer is now full of versions setup files. I am arranging to version? which trainer use which version. Can you imagine? I created the files trainers uses version. Last version is not working back versions. This is strange. I am trying to still understand. If I see some trainers or sb. I have to ask first this question… Sir or Madam which version do you use ?
Actually I used on website Mendix Studio. Not the pro. I am using also another training program. But I will try to explain more. Let me study again with patience.
