Obi wan was bending the truth about lukes father anyway. He could have just painted a pretty picture for luke. Leia is strong with the force she could remember her mother PLUS. My family had pictures of me doing things when I was a baby and they would explain how it was. Then I believed that I had remembered it. So Leia would not have been lied to about her mother. She was well informed to who Padme was. What is wrong with that? So really it would be a continuity error only if Star Wars was set in OUR UNIVERSE. The only thing in the saga that should be removed is Jar Jar Binx, annoying CGI characters, Midiclorions.
