Curves "settings" retention issue

I have used curves since the early days. 2022 introduced a bug that has been in place for 6 months now. 

The curves dialog eventually starts losing settings upon reopening and the result is a dialog box stating the parameters of the point and then the loss of that point and a new default setting, which clobbers the original setting (which was lost).

1: Open an image file.

2: Create a curves layer

3: Set multiple points on the curve.

4: Close the curves dialog box.

5: Open the curves dialog box and try to move a point.

6: Repeat until the failure starts occuring.

I am under the assumption that there is a issue with preserving curve data across module invocation. Somewhere the "preserved" curve settings is getting clobbered or not properly loaded.

Please fix this.

It is absolutely annoying I have to play "tag" with software defects.

I am running windows 10 on a Thinpad W550s and the latest version of cloud photoshop.
