Expected Behavior vs Actual Behavior

Expected to return a new list of settings with different options set.

Actual behavior returns a list of setting set duplicated.

Steps to reproduce - Ensure to include actual links!

1. Clone repo locally
2. Checkout to dev branch
3. poetry install
4. poetry shell
5. spotdl web
6. In the web-ui, go to settings, and choose a lyrics provider different from genius which is the first one on the list. i.e. musixmatch, azlyrics
7. Save the settings
8. Go to the console, and see the log Applying settings followed by a json and see the lyrics provider has duplicate value.

Closing this issue as I have traced that the issue is not on spotdl but on the web-ui.
