New Gmail Calendars Not Being Displayed

Sep 11, 2015
I have a Mi4i and the xiaomi.eu_multi_ferrari_5.12.24_v7-5.0 the problem is i have several calendars on my gmial account (inclusive facebook birthday calendar) and this calendar is not available to select on native calendar app of my Xiaomi Mi4i.
I have tested install other calendars (such sunrise) and the facebook birthdys calendar of my gmail account is displayed. Is there any fix for this?
