Month Year Template issue

[Coloful_Black]

Hi gurus.

I  have  a data set with a column of month like this...

the template is general ....when I load into qlik , It does not list in a calendar order; I guess the system recognize it as string....

without changing script , is there any quick way to make it as a good calendar template? 

I tried expression date with format of 'MM-YY', it did not work.

thanks
