Farmville 2 Levels

I'm on level 65 when I play farmville 2 on Facebook but only on level 8 when i play on Zynga. They were on thesame level but my sister cleared her browser history and I think that messed it up and put me back on level 8. I had restarted playing on Zynga when I thought I had to start over but realized I hadn't lost everything on Facebook. It happened before when I played on google but I found when I played it on google chrome it was back to the level I was playing on FB. Now it has me back to level 8 on Zynga. Is there anyway you can delete the level 8 game and match the zynga game to Facebooks level 65. I love playing this and have way more fun playing it through Zynga. Thanks, Edie Exley
