OnlyOffice keep flag form input field as required while is entered

Do you want to: Ask a how-to question
I don’t know what i am doing wrong. In the template creation phase i select the input field in the form as required.
When i compile the document the editor keep saying that the field is required while is right filled. What i have to do? The “submit” button is grayed out for this.

This is the creation tof the template phase

Another question. It is possible to not show this message every time i open a docxf file with onlyoffice?
