For splitting the values in Qlik we have 'Subfield' function.
Subfield (text, delimiter, field_no)
Subfield (FieldName, delimiter, field_no),
Now Let's talk about your table.
Subfield(Values,',',1) as Values
It is better to define field_no in the third parameter.
I have also attached example app. Hopefully, this will solve your problem.
