Thank you Adam, That fixed the problem. Well done!!!!

1. I am on a 1920 by 1200 Retina screen. I have been through all the zoom levels to no avail.
2. Already using default twenty twentyfour theme. Deactivating all plugins except the two Rankmath ones made no difference.
3. WordPress Dashboard > RankMath > General Settings has no option for Editor
4. Tried using chrome but it says my password is wrong. I don’t want to clear my cache, there is useful stuff there and last time someone pursuaded me to clear it it took me 3 weeks to get back to where I was. Can’t WordPress have an option to clear only its own data from the cache?
5. Tried clearing both but still same problem
6. I eventually found one of the three dots which was not hidden and clicking it allowed Rankmath to be selected. I cannot see the panels section in preferences. I can at least continue for now by clicking on the single dot, so thank you Khan.
