Saving to Perspective Dashboard from Designer

I need some help. For some issue when i'm done making changes I try to save all and nothing changes. It's on my Home page. Not sure exactly what is going on. Yesterday I was able to save but when I woke up this morning the page reverted back to its old self. Hopefully someone can shed some light.

Thanks

Do you have more than one developer working on this project? Sometimes, if we are not careful to import changes from the gateway prior to saving, we end up overwriting each other's changes.
