Can't go back in Time Machine
I wanted to restore a file from Time Machine (Ventura 13.2.1 M1 iMac). I opened my Finder to Applications and selected the file I wanted to restore. Then I clicked on Time Machine/Browse Time Machine Backups, and tried to scroll up on the side. I could go up a few hours, but when I tried to select a date from last week, nothing happened. I hit the up arrow next to the finder, and nothing happened. Now that I am done, I see the icon in my menu bar is white. It was black before.
What's going on? Why can't I get back to last week's backup?
