Coupon price condition not working

Hi All!!!
There seems to a bug in coupon authentication. Lets say if I add coupon only to 1 category and put a condition that it should be applicable on purchase of Rs. 500. But customers are adding 1 product worth Rs. 400 from that category and another product worth Rs. 100 that is not added in coupon condition. Still the coupon gets applied. PFA for the screenshot wherein the coupon has condition that it should be applicable only on 12 Red and White Roses and value should be atleast Rs. 550 to apply coupon. But customer has added another product from different category (that is not added in coupon) and gets the discount.

Is there any way to solve this issue? Please Help!!!

Thanks

It's not an issue at all, everything works normal. Order Minimum is PER CART, not per category. So your cart meets the criteria perfectly.

If you want better control of coupons, I'd suggest you to use Advanced Coupons extension. It is much more flexible and you can define per item order subtotal, as you wanted to.
