All matches are loaded when app is restarted

When restarting the app it seems that the league header is not properly set and reloading the matches leads to all matches of the GameDay being loaded.

Steps to reproduce

• Close the app completely
• Start the app
• Select a GameDay
• Reload the matches -> all matches of the GameDay show up

Steps to "fix"

• Go to the "Settings" tab
• Select any League (i.e. set the header)
• Reload the matches and see that only the relevant matches are loaded
