Gallery package : multiple tv gallery item

Hello

I'm using Gallery package and link some gallery pictures with my resources with a tv which has gallery item type.

My problem occurs when I use multiple tv's having this type :

Example

1. mytv1 : galleryItem containing image1
2. mytv2 : galletyItem containing image 2
3. mytv3 : empty
4. mytv4 : empty

But when i save the resource, mytv3 and mytv4 will be filled by the mytv2 datas (the last populate one). So when I update the resource, all the myth will be filled even If they were empty.

Any idea to reset to keep the tv empty?

Thanks
