Two versions of Essie Hard to Get?

Today I went to a different Trade Secret to see if they had any more $2 Essies. They had quite a lot, but only a few that I haven't picked up yet from the other one. I got this really pretty pale pink(shown on the right in the picture) When I got home, I realized that it had the same name of one that I picked up previously. I wasn't able to remember the names of all of the Essies I picked up.

The Hard to Get on the left is so much more pink than the one on the right.

The labels look different. I wonder which one is newer, or if the labels mean the formulas are different.
