Any idea what is causing it and what can I do to correct the issue?

Expert Response
Sand cherries can be affected by common cherry and rose diseases because cherries are in the rose family.
It looks like a fungal leaf spot disease is affecting your shrubs. The high temps and humidity we have experienced this summer promote fungal diseases. Management information is included in the references.
