Help – Error with CouponID – Google index duplicates 2000 times.

Hello everyone.

I am currently experiencing very serious bug with Theme Coupon
For people to understand what I am having serious error , please see below:

Here is my store: https://eventscoupons.com/store/edrawsoft-coupon-codes/

As you can see it only has 7 coupon codes. In the robots.txt rule I blocked couponid and did not allow google to index the coupon.

But today when I checked with the command: site: https://eventscoupons.com

Google has indexed this Edrawsoft store with 4000 results.

https://www.google.com/search?q=site:eventscoupons.com&ei=kUGPW9qSK5jj-AaKipfAAw&start=70&sa=N&biw=1280&bih=854

– You can check page 10, 11, 12, 13, 14, …, etc.

All urls are the same – the only other showid. It duplicates over 2000 times.
This is bad. My coupon theme is ver 8.9.6
Anyone who has encountered this error please help me. I sincerely thank .
