Mistake in a "Say It Right" graphic

I noticed in the Initials and Finals videos that whenever a graphic of the Chinese Initials and Finals was displayed that the last row of the finals chart reads: un, ün, ang, eng, ing, ang. I believe the last final is supposed to be ong, not ang.

yes, you are right. the last row of the final chart is :un,ün, ang, eng, ing, ong.
