Sounds to me that you did not cook the jelly long enough--you said you boiled it for only 1 minute. If you didn't test it by temp or do the freezer gel test, that was where you went wrong.
I would remelt it with some water, bring it back to a boil, do the gel test and then, reprocess it. You will need new seals for your lids and everything else will have to be scrupulously clean and hot before you refill the jars and reseal. You will have to reprocess in the waterbath, too. I would definitely do this unless you want concord grape syrup for pancakes and waffles.
