Odd. I use tdb:unionDefaultGraph all the time with no FROM/FROM NAMED,
at least programmatically.
Assuming you are running on up to date code then you may want to try a
simple test case with two small test graphs and a trivial ?s ?p ?o
query.

How can #4 be in a different graph to #1??
Perhaps if you can generate some minimal example test data with just a
few statements for P and I, that would explain what you want more
precisely and give a test case that others could try out.
