How to use update extractor from data result view?

In the new version of the tool I cannot generate updates statement from tables that in the previous version worked ok. The problem is that the resulting statement does not include the table from the executed query but a default table name "MY_TABLE". Table from the query does have a pk.

Here is a short example:

-- Prepare test table
create table tmp_test2 (
  a int,
  b varchar2(50),
  constraint test2_pk primary key (a)
);
insert into tmp_test2 values (1,'2');

-- executre statement
select * from tmp_test2;

-- returnint result from update extractor (ctrl + c)
UPDATE MY_TABLE SET A = 1, B = '2';
