Black lines, bottom & right side

I have used this app for years now and have had no problems ever. Until now. I get these weird black lines at the bottom edge of the photo, as long as the right side edge of the photo. This happened about 3-4 months ago, please fix asap. Stopped used this app for this reason and and considering downing something else. Nothing else fits my needs tho as this app is so simple & basic & its why I am such a constant user. Running iOS 9.3.3 & have the latest version of square fx app.
