Tokens with same content will be deleted when other tokens with same contents deleted by using backspace key. Plus, only the tokens in TokenizingSample have this problem.

Steps to reproduce

1. Create tokens like Pic 1 below.
2. select a token having same content with at least one token.(In the picture, we select "Account")
3. Press backspace, all tokens with same content will be deleted.
P.S.: if the token is not in TokenizingSample, the bug won't be reproduced, Pic 2 below is an Example.
