That's because you did it wrong.

You didn't "change" any (master) record, you entered a brand new one.

This is how it is supposed to work: while in master block, enter query mode. Enter search criteria (there's no problem in selecting it from a list of values you already have, just REMOVE the whole "IF" clause from the trigger). Execute query.

Both master record and its detail records will appear. Now you can change these values, delete them or insert new ones.

That's it.

What you did was: you didn't enter query mode. You selected values from list of values into a master block (which - as far as Forms is concerned - you entered a new record. You didn't fetch the one from the database). EXECUTE_QUERY fetched details because of relationship that exists between master and detail block.
