Script executed but data not persisted

2. BEGIN
3.   FOR foo IN (SELECT * FROM FOO) LOOP
4.     INSERT INTO BAR (ID, STATUS)
5.     VALUES (foo.ID, foo.STATUS);
6. 
   
7.     FOR foolog IN (SELECT * FROM FOO_LOG where ID = foo.ID) LOOP
8.       INSERT INTO BAR_LOG (ID, REV);
9.       VALUES (FOO_SEQ.CURRVAL, foolog.REV);
10.     END LOOP;
11.   END LOOP;
12. END;

The problem is: liquibase runs the script but no data is persisted to the database, it looks as if the script doesn't run. If I introduce a typo on purpose (change a table name for example) the script fails to run so it does actually execute the script. Also, when I run the SQL manually it works as expected so it seems that the problem is related to liquibase. 

Any clue of why this happens/how to solve this?
