No rests

Hi, how do I input rests in this situation? If i input notes everything seams to be OK, but if I delete them - there are no rests again. I tried to input rests their self - no success. I cannot set start voice, because there is nothing to select. I tried to input note, select start voice and then delete them - no success. How do I solve it? Thank you in advance.

Type ‘rest’ in the Shift B popover. Or turn OFF Starts Voice on the first note.

Thank you very much for such quick replay. Turning off start voice on a first note solved it😊
