Photoshop 21.2: Clipped adjustment adjusting entire image

Just updated Photoshop today 6/16/20 (Windows version).  I'm working on a file with multiple layers including multiple image layers.  I added a Hue/Saturation layer above one of the image layers and CLIPPED it to the image layer below.  But when adjusting the Saturation slider the ENTIRE IMAGE is radically affected instead of only affecting the layer below.  In the History Panel I returned to the original image version to start over, then added the H/S layer again.  This time it worked correctly. So the problem doesn't seem to repeat.  But if I close the file without saving, then reopen the file and try again the problem WILL repeat.  Don't know if there are other bugs as I haven't had time to explore.  Just found this one right after updating PS.
