Why did my photo go in the wrong album?

I have an iPhone, so I upload photos to FB using that. They've always gone in my iOS album, and I've never had any problems until yesterday. A photo that I put on FB using my phone went into an album called mobile uploads (that's an existing album from before I got the iPhone). How did this happen, and how do I fix it? Do I have to reupload the photo, or can I move it to the appropriate album?

Mobile Album is Usually The Default Album That it Goes Into When You Upload From Your Phone

You Can Move The Photo To The IOS Photos To Do That Go To The Photo Album Click Edit Album Then Where The Photo Is Click On The Arrow On The Top Of The Photo Click Move To Other Album Select IOS Album And Then It Should Be Moved To That Album
