I have checked the legislation and there have been no changes to ESA in regard to a claimants commitment to attend WFIs and participate in Work Related Activity, if you are certain that you are in the Support Group then you are not required to do so.
My best guess is that the Decision Maker has taken a standard letter intended for WRAG awards and has used it to notify you of your SG award.
You will have to wait and see whether you receive a further letter, but I think it likely that you won't.

If I were in your position I would write to my MP enclosing a copy of the letter that says you are in the support group but required to attend interviews, and ask him to write to DWP to get clarification.
From my own experience, any letter I send direct to the DWP seems to go straight to the waste bin!
