All of a sudden when I go to the default new form in a simple List the form appears from right side in a modal (does not redirect to NewForm.aspx).. Here(and also in NewForm.aspx) I see a new field Content Type with one option in dropdown menu Item. Why is it so? I used to set Allow management of content in List setting to Yes to change column orders but because of this there was never an issue. Have the settings been compromised? Kindly help!
I'm working in SharePoint online
UPDATE With Classic SharePoint experience this problem does not appear
