WD Photos is showing pics that have been deleted

Hi guys,
i know that WD Photos is ritierd and so…
but the My cloud app is not usful as the old WD Photos app, sincse it cant orgenize the photos as the WD Photos app.

i have some strange issue, when i’m deleting a picture, i still can see it through the WD Photos but not on the PC or on the My cloud app.

i’ve tried to delete the app and reinstall it, and tried to serach for some cach folders on my phone, ended with no result.

though maybe some one of you could help me

using Galaxy S 7

any one?
