Insert, select and create table as give different results

Question

Hi all
I have a strange situation with this three cases:
1) select statement: SELECT (...)
2) insert statement with that same select as above: INSERT INTO SELECT (...)
3) create table statement again with that same select: CREATE TABLE AS SELECT (...)
Each of these cases produce different number of rows (first one 24, second 108 and third 58). What's more the data for second and third case doesn't have any sense with what they should return. The first case returns good results.
One interesting thing is that select uses "UNION ALL" between 2 queries. When simple UNION is used, everything works fine and all three cases return 24 rows. Also if each query is run seaprately, they work fine.
Anyone encountered something like this? (before i create an SR :)
Database is 10.2.0.2 on AIX 5.3. It's a data warehouse.

I understand UNION vs UNION ALL. But that doesn't change the fact that same SELECT should return same set of rows wether in INSERT, CREATE TABLE AS or a simple SELECT.
DB version is 10.2.0.2.
Here is the SQL:
INSERT INTO TMP_TRADING_PROM_BM_OSTALO
