Click on the size area (992px 37.3% in your screenshot. Then click the “Reset” icon as shown in my screenshot. Do this for each of the different screen sizes.
After some more experimentation, it appears that any changes made to the screen size settings are not currently maintained after switching to another screen size (that is also the same for me) so unfortunately it does look like you may need to keep doing that.
I’m thinking that if someone updates the size of each breakpoint that it should be maintained by the system but currently the updated screen sizes are lost when navigating to a different breakpoint. Certainly the way the “Tablet” screen is set to different sizes, depending on where you clicked immediately before clicking on it, looks like a bug.
Well that makes me feel better. I thought it should be a simple fix. It is odd how if I go from Horizonal Mobile to Tablet it’s correct but if I go from Desktop to Tablet it’s wrong.
Thanks so much for your replies today, I so appreciate the help!
Do you normally use your browser zoomed in? The small magnifying glass icon in your address bar shows you’ve enabled zoom:
I can’t say for sure if this is the issue, but I know this can cause some wonky things with the in-Designer scaling feature so I’d try disabling it to see if that fixes the issue.
You can either click the magnifying glass icon and then select “Reset” or you can use the shortcut CMD/CTRL + (-/+) and you will cycle through the magnification levels.
