Hello,
I have 7 page items in one page all are checkbox group. I am passing this values to another page on on button click. My branch configuration is as below.

By Default the report will be genearted considering no special filters applied meaning entire table data will be pulled.

When i have something selected on all items i get the values passed correctly as below

But if i dont select any one of the item i was expecting the value to be \ but instead i was getting comma(,) and the next value is passed to the previous one. as below. In this i didnt select anything for PR but it takes , and gets the values of AJCC and everything get switched.

Can anyone please help me on how to fix this?
Thanks!
