Unique value using RegEx formula not working

[TapasDas]

Hi,  

I am new to Alteryx and trying to find unique values in a particular column separated by comma.   While I used available Regex  formula for my case, I found two unique values are merged and reporting only one value.   Attached example..   Appreciate any help on this.
