Because the Table Designer is seriously buggy, and has number of
severe design flaws, and the empty transactions you see are a token
of these.

These empty transactions are harmless, however, say that you change a column
to a table that both references other tables, and are referred by other
tables. Now these transactions will no longer be empty, but will
comprise different parts of the table-update when it all should have
been one transaction.

Don't use the Table Designer to modify tables, use T-SQL instead. OK,
so you could generate scripts from the table designer, if you review
them *carefully*.
