Sublime, how to Find & Replace All for all documents in a project

I'm working in a large folder directory in a Sublime project. When I do the Find & Replace All feature within the Find window, I'm having trouble saving to all the different documents.

In the past, I've just double-clicked on the document (within the Find window) and saved the document individually. I've also tried to go to File -> Save All, but it doesn't seem to save everything. I'm wondering if there's an easier way to Save All the changes. Any help would be appreciated.
