Cannot set ETV using a refresh view

Dear all,

It seems that setting an ETV through an SQL view doesn't work as expected or I do something wrong!

I start a program by using a customer activated step(I need to track Opt-In).

After this step, I use a GetData step in order to set data to an ETV(Name:CONFIRM_IP).

I use a simple SQL statement (please check the below screenshot).

After GetData, I use s SetData step in order to set the ETV value into a Profile's list field. But the field remains empty.

Please note that I use both fields RIID_ and CONFIRM_IP(extracted field which is mapped to ETV field) as DEK and that the extracted from SQL field has the same type (TEXT) with ETV and the Profile's list field which I use in SetData step.
