Over the past month I’ve noticed that my batteries have a tendency to swell after a charge or doing a factory reset and normal flights. Two of my four batteries have suffered from catastrophic critical low battery failure, any help on why this is? The batteries are less than a year old

Can’t answer your question... but I would contact DJI and/or seller, plus I would retire them from flight, even if used for updating,etc.

Uggh, I’ve had it. I’m selling this drone and buying a skidoo or an Autel

Is this a rather frequent issue with the Mavic line? I've got a Phantom that sits on a shelf because I had zero luck with the batteries, but a Spark that has had 0 issues. Have been considering an Air, but would hate to replace the Phantom with one trying to escape bad batteries, just to run into them again.

I have 10 batteries, each with over 200 hrs flight time and have only had one show swelling as well as very short (< a minute) flight times the others are working fine.
As a general trend I have noticed that the original flight times were 25-26 minutes and now are only 22-23 minutes in calm conditions.

It can happen to these brands as well, it's an issue with all li-po batteries

So far I have had good luck with all my batteries from DJI. I have just the original one on my Mavic Air and two for my Spark. However I am very familiar with how to take care of batteries and understand care is different for each type of battery. I suggest checking out Basic to Advanced Battery Information from Battery University for more information than you probably want to know.... If I saw a battery swelling, I would get rid of it quickly and safely and purchase a new one.
