Here are some common solutions to removing extra, blank pages:
Delete Empty Text Fields
Text fields can still take up space on your menu even if there is no text entered and can often create an unwanted extra page. Remove all the extra empty text fields from the Text tab clicking the X as shown below.
A blank page may be the result of inserting a text break. To remove breaks, click the Format tab, select the section on the menu preview that you'd like to move to the previous page, then click remove breaks.
Turn off Menu Covers
It is possible that a front or back menu cover has been turned on. To turn them off, click the Setup tab, then Page. If a cover is turned on, the button will display in teal. Simply click the button to turn the cover off.
