Elements 2023 Shadow & High Lights preview/ Spot healing brush issues.

I have an Imac running IOS 11.7.1 I am using Elements 2023. There are two bugs I am encountering. When lighting shadows, I have to toggle the preview box twice to see the result. It works but takes an extra stroke to see the result. The other issue when using the Spot healing brush tool, it sometimes slows to a crawl over what you are trying to heal. Other than that all is well. Any ideas?
