Why don't you bleed it again, following the repair shop instructions?
...Pressurize the system, keeping the pedal pushed to the floor (broom stick..), then open the bleeder on the slave for 20 seconds (..!!) yes, that's what the shop manual says.
The only associated cost would be two litters of brake fluid (as 20 seconds feels like an eternity), but may solve your problem.
