Continuity mistake: After spilling the sauce on the floor, when Miranda is discussing with her boyfriend her bag suddenly disappears from her shoulder. Later on it magically appears on the floor.
Continuity mistake: When the tomato jar crashes on the floor, the splatter changes shapes between shots and the label disappears in the second shot.
Continuity mistake: When Miranda drops the paper bags on the floor a lettuce and a bottle of water fall out. Seconds later the stuff changes completely: The bottle is gone, the bags are in a different position and, best of all, Miranda's leather bag (which was previously hanging on her shoulder and suddenly disappeared between shots -listed mistake-) magically reappears on top of the mess.
Answer: I'm a long-time fan of the show, having re-watched it many times, and I definitely remember slightly different dialogue at the end of that episode than what's on my DVD. I'm afraid I have no idea why this change might have been made or any other info, but you're not insane.
