If you make changes to how things are displayed, they'll be carried over when you navigate to another folder in the same window, if the next folder is still using the same format as the previous one. (This is so you don't have to keep reapplying the same changes every time you navigate to another folder, should you want to look at things in a different, ad-hoc way sometimes.)
Opening a new folder tab and closing the old one is one way to throw away those remembered changes, but you could also run the
Set FORMAT=!folder command to do the same thing (and load the current folder's format).
Or, you could make a button which runs this command:
That would save the format for the current folder, and then re-load it and remove any temporarily remembered changes.
(Actually, I'm not sure if you need the second line. The Folder Options > Save button will effectively do both lines at once automatically, at least. If you're using commands to save the format instead of the dialog, I'm not sure if it does the extra step without making it explicit. I'd have to check. But using both lines won't hurt either.)
