Premiere Elements Windows 10 problem with preference settings for preview

Hi community!

I use the german version of Premiere Elements Windows 10 Pro, so maybe some things will not be trranslated exactly.

I have this problem with the settings for the location of preview files (video and audio preview):

- The default setting for this preferences is "Same as project"

- I change the settings to a directory on another disk, assume e.g. "D:\Premiere_Preview"

- I create a new project, make all project settings, save the project

- I check the preferences and they point still to "D:\Premiere_Preview"

- I import media, put it into the timeline and do some "Render"

- The preview files are correctly stored below the "D:\Premiere_Preview" directory within a new directory with the name of the project (ProjectName.PRV)

- I save the project

- I exit Premiere Elements

- I check the "D:\Premiere_Preview" directory and the rendered files are still there

- I restart Premiere Elements and load the project

- The render areas on the timeline now have changed their color from green to orange (same like not rendered)

- I check the preferences and they don't point to "D:\Premiere_Preview" anymore, instead their setting is back to "Same as project"

I have tested this on two different Windows 10 systems, the problem is the same on both systems.

Any ideas what is going on here?
