Appoinment pagination monthly steps

Am I reading this wrong

Shortcode:[app_pagination]
Description: Inserts pagination codes (previous, next week or month links) and Legend area.
Parameters:
step: Number of weeks or months that selected time will increase or decrease with each next or previous link click. You may consider entering 4 if you have 4 schedule tables on the page. Default: "1"
month: If entered 1, step parameter will mean month, otherwise week. In short, enter 1 for monthly schedule. Default: "0"

so my code is
[app_pagination step='1'] or [app_pagination step=1]
tried both but the buttons still show next week / prev week
