Widgets inverted auitomatically?

My widgets automatically inverted the contrast and now I don't know how to get them back to what it was before: light background with dark text or graphic.  The watch's face is still correct as before: black text with white background.

Does anyone know how to invert the widgets back again or if there is a setting that I can toggle to de-activate this automatic inverting?

What I did at the time it happened was:

  1. I wanted to see what the watch indicates as solar intensity if only half of watch's face was exposed to the sun.
  2. I navigated to the Solar Intensity widget.  It showed a full sun as I was standing in the direct bright sun
  3. I placed my other hand over half of the face's watch for a short while.  The small circle changed as expected to show less sun.
  4. I removed my hand and the circle showed a full sun again.
  5. I repeated this one more time.
  6. Then I noticed when I scrolled through my widgets that they are inverted.
  7. I thought that this is a setting that kicks in during night or dark rooms, but now, one hour later, they are still inverted.
  8. Removing a widget and re-adding it does not fix it.

Any ideas how to have again widgets where the foreground is black and the background is white?

The watch software version is 13.20

Thank you
