Gleam Competitions

Molly4

Good Morning
I am not sure if anyone can help me with this or do I need to go direct to gleam.io
I regularly enter Gleam/Rafflecopter competitions and don't normally have a problem. I just work my way through the entry options using the Facebook, Twitter, Instagram, Pinterest etc. entry option.
Recently when I enter one option it wipes out my entry for the previous options and I have to start again. For example I have just entered a Live For Films competition. 
The first category was Twitter. I had to link my Twitter account first even though my Twitter account is already linked to Gleam. I then worked my way through the Twitter options. Next was Facebook. When I clicked on the Facebook option it wiped out the previous Twitter entries and I had to redo them all again.
Another problem is clicking on a YouTube option which will wipe out all my previous entries as well. This particular Live For Films competition didn't have a YouTube entry so that didn't happen today. 
Does anyone know why this is happening and how to correct it?
