LR showing in all photos left corner

Hi,

I've used this app for years but recently any time I go to upload a picture in my "favorites" it's shows LR in the left corner of every pic and usually it doesn't show that unless they've been edited and saved in Lightroom. Pictures I haven't even edited yet have that symbol in the corner so it's really hard to distinguish what's been edited and what hasn't because in the past only pics that have been edited have that simple in the corner.
