Samsung Calendar multiple reminder option gone???

Hello, I have been using the samsung calendar for a while now, and HAD a default set up with my desktop Google calendar for 3 diffrent reminders on each so I dont forget,oversleep etc. anyhow It seems that when Google calendar STOPPED sending SMS messages earlier idk this month or last month I have NOT been able to set up more than ONE reminder even from a appt set from my phone, after the first reminder is set the green plus sing is no longer there to add more. I CAN go into older appt's and edit and the multiple reminders are still there and the green plus to add more is there and selectible. I am assuming it has something to do with the google calendar so what is up?? HELP PLEASE Thanx Kat:'(
