1st off,never boil pre-hopped LME for any length of time. It'll drive off hop flavor/aroma leaving whatever bittering was there at the length of time the hops were boiled originally. Use the steeped/PM'd grains for the hop additions. Then add the pre-hopped cans at flame out,stiring till no more can be scraped off the bottom.
Everything works if ya let it-Roady(meatloaf)
