I don't know about the blackberry Morgan, I only have the orange marmalade....it's just ok to me. Not spectacular. Than again I don't think any store bought jelly or jam is really that good. They all have that sugar sub after taste to me
Mine is a little runny too. But then It's been years since I have had the real thing Haha! I bought that and some Polaner sugar free Strawberry preserves and I'm not too impressed with that one either. Either of them aren't too bad though when I mix them in things. They work great mixed in the one minute muffins for flavor and even just some cream cheese or whipped cream
So basically I just like them for use in recipes.
It's just easier and tastier to make my own when I''m wanting something to spread. Here is a couple of ideas.....
You can just reduce the fruit down on the stove top and sweeten with xylitol or zero.
You can even get the sugar free canning pectin to add to it and freeze.

http://www.macspride.com/products/JAMS-AND-PRESERVES-%252d-NO-SUGAR-ADDED.html I should say that I have only tried their strawberry and apple butter. Both are pretty good and pretty much what you would come up with if you canned it yourself using the sugar free pectin. I see the web sight doesn't show the nutritional value for them....The strawberry is 1 net carb per 1 Tbs and the apple butter is 2 net per 1 Tbs if anyone is interested.
I'm sorry if I haven't helped much with your question...it's just my 2 cents
