Another quirk of Bridge 2023

Yesterday I reported the flawed preview system in Bridge - today I find another preculiarity.  When backing up a folder to my portable hard drive by dropping and dragging, Bridge deletes the folder from my PC.  Ok it's on the hard drive but to keep it in both places I have to use the "copy to" command.  But this isn't consistent - sometimes Bridge deletes the source folder and sometimes it doesn't.  I really think Bridge 2023 needs to revert to 2022 while all these silly little issues are sorted.
