Hi,
I'm pretty sure i can solve your issue, but as this is a paid plugin, let me give you a recommendation. I am pretty confident Gravity know about this issue and are in the process of updating. If they are not, they for sure have someone on their forums that have found the same issue.
I would recommend checking that first before you pay any money.
If you need any asistance or additional info, just contact me through freelancer chat.
