I can't reproduce this. I'm testing with bash-5.2.

I get, broken into different lines for clarity:

$ mv Buehrer\,\ Ted/    [after the first tab]

$ mv Buehrer\,\ Ted/How\ to\ Listen\ to\ and\ Appreciate\ Jazz\ \[TMS\]\ 
\(2006\)/		[after the second tab]

(Note that default completion stops at directory boundaries; I'm not sure
how you got multiple directory names completed with a single tab.)

Then you add the space and start a new double-quoted argument:

$ mv Buehrer\,\ Ted/How\ to\ Listen\ to\ and\ Appreciate\ Jazz\ \[TMS\]\ 
\(2006\)/ "Buehrer, Ted"/	[after the third tab]

$ mv Buehrer\,\ Ted/How\ to\ Listen\ to\ and\ Appreciate\ Jazz\ \[TMS\]\ 
\(2006\)/ Buehrer\,\ Ted/How\ to\ Listen\ to\ and\ Appreciate\ Jazz\ 
\[TMS\]\ \(2006\)/	[after the fourth tab]

Note that bash/readline default completion requotes the entire pathname
once there is another directory name requiring quoting.

Now, this command will obviously fail because you're trying to move a
directory name to itself.

Quoting differences aside, these are identical directory names, so the
`mv'is going to fail regardless. But why would you expect bash or another
application to change to that directory?
