Deleted picture can't be removed from gallery

[likuna]

My phone is Samsung Galaxy Note 3. A little while ago, I've taken a picture using Retrica app and then deleted it using Retrica app as well. But when I go to my photo gallery through gallery icon and open retrica folder, the pic is still there; though, it looks like this (see the photo). When I try to delete it, nothing happens. I even cleaned photo with clean master but the photo is still there.

please help me!! I really want to remove it!

Can you find the folder that Retrica saves photos in using a file manager app (either MyFiles or a 3rd party app like ES File Explorer)? If so, look for the photos--is it still there?

If you can't find the photo anywhere, try going to the App Manager, select Gallery, and Clear Cache/Clear Data, then Force Stop. Now open it again, and wait a few seconds for the database to rebuild. Is it still there?
