The league selector in the setting does not allow me to select or it remains bl

Greetings, thankful for this fabulous plugin, but I have a problem, When I select the box to use links in the link options, The next item that says: “Standard link for new users”, does not allow me to select any, so when I go To create a game, or create a new league, I am told in a warning that “Important: at this moment you are not using leagues. This may be caused by the fact that you did not add any league in the administration or because you changed this setting in the plugin options. “, when selecting the link that is the configuration, it continues in the same condition.

I hope you can tell me what the problem would be and if I can solve it, I will also help you later on the Spanish translation, thank you.`
