How to set a shadow for a rectangle in Adobe Photoshop?

Question

Adobe Photoshop

Good afternoon!
Not long ago I encountered such a problem in the Adobe Photoshop editor that if you create several rectangles and set a shadow on both of them, and if you start to edit the shadow of only one rectangle, then the shadow on the second also changes automatically. And also, if you create one more rectangle and start to edit the shadow on it, then at the same moment the shadow changes on the rectangles that were created earlier.
Who knows how to fix this?

If we are talking about the degree of angles - then it is possible that the matter is in global illumination.
