QML ApplicationWindow: Binding loop detected for property (multiple variables)

I am quite new in QML, but I have done first sport tracking app which seems to be working, however I am having multiple warnings on each screen of binding loop... app seems to work quite fine actually.

As soon as I run the app, I have these errors:

Code:

I am very interesting to learn how to declare and use variables properly!

If there is any tips from you guys how to improve, would be much appreciated.

Here is the relevant code:
