Project settings > allow only one subtask : "save" unvailable

Hi @creecros

My question dealt with this part of the documentation : https://docs.kanboard.org/en/latest/user_guide/settings.html

I can enable this option, it works, but when the dialog box appears, users can’t save their choice (“save” or “cancel” doesn’t appear on web page) ? As a result, the situation is blocked.
