InDesign displays the current zoom level in the tab with the document name in the upper left. It also displays the zoom in the status bar at the bottom of the window. Why are these different numbers? The tab is 100%, and the status bar is 66.67%
In my experimenting, it appears to go away if I go into InDesign preferences and turn off UI Interface Scaling. When I turn it back on, the numbers begin to disagree again! Interesting! It does not seem to be affected by changing Win10 text scaling in Display Settings.
So, if I turn it off in InDesign, and turn it up in Windows 10 Display Settings, I can get to a work-around that keeps the tool panel big enough to see, while keeping the Zoom numbers in agreement.
We all learned something here today! 😊
ok, we found a reason why this mismatch of zoom percentages happens.
But, that does not mean, it is no bug.
I would suggest you to do a bug report:

found your bug report and voted for fixing it:
When UI scaling is active Zoom level is no longer accurate in both displays.

I didn't learn enough, evidently. ☹️
One of my students is dealing with this now... so where is UI Interface Scaling in InDesign Preferences?
