Scaling factor text doesn't properly update when reverting to previous configuration

## What Happened
After changing the scaling factor from 1x to 2x, I was then prompted to decide whether I want to keep or revert this configuration. When I chose revert, one would expect the text to change back to 1x. However, it instead remains incorrectly displayed as 2x.

## Expected Behavior
Scaling factor text is updated when configuration is reverted

## Steps to Reproduce
1. Open System Settings
2. Open Displays
3. Change scaling factor from 1x to 2x
4. Choose option to revert to previous configuration
5. Observe "scaling factor" text in bottom left corner
