There are a couple of things that cause a beer to have a malty flavor, when it wasn't intended as such.
One is that using extract sometimes means a concentrated boil, and the result of that is a "cooked extract"y malt taste. The fix for that, if using extract, is to boil more wort when doing a partial boil, and adding the bulk of the extract at the end of the boil. That reduces maillard reactions, similar to caramelization.
Another is simply recipe related, as the balance of the beer is crucial. It could be underhopped, and that will result in a sweet beer.
Fermenting at 72/74 could be an issue as well, as that is on the warm side for most American ale yeast, so cooler would result in "cleaner" flavors.
Water chemistry can play a big role in the perception of bitterness and/or maltiness as well, so it would be good to know the water make up for these batches.
Lastly, making a bitter beer when doing a partial boil (if that is what you are doing, boiling 1/2 of the wort and then topping up with water) is hard to do due to the way hops are. Only so much of them will isomerize, and create bitterness. If you're doing a partial boil on the stove, that could be a big part of why the beer seems underbittered.
