Describe the bug`
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. Go to https://streak-stats.demolab.com/demo/
2. Click on Username input and type some text
3. Press enter
4. Observe some advanced property is added implicitly

Every time you press enter (i.e. submit form) the next advanced property is added with the same default colour.

Expected behavior
Advanced prop is not added. It should only be added explicitly, when user adds it manually.

Desktop (please complete the following information):

• OS: MacOS
• Browser: Chrome
• Version: v109

Additional context
Overall, implicit adding of advanced properties with the same value (in our case - colour) make the final result not readable.

I will open a PR soon with some improvements.
