Multiple collections when trying to save

Recently when adding a new recipe to a collection, I noticed a few collections I didn't recognize... it turns out they are my family members collections.
For example, I have a collection named "Chicken recipes" and my sister has a collection named "Chicken". When I went to add a new recipe the other day, I quickly added it to "Chicken" and I was confused later when I went to find it in my "Chicken Recipes" it wasn't there. (I didn't understand at the time I could add to my family members collections). So now, whenever adding a new recipe to a collection, I am unsure if it is MY collection or someone else's! Is there a way to just have MY collections show up? Or a way to Identify other people's collections from mine when choosing?
