Hi! Sorry for the late response. Yesterday, they were saving via action just fine, to sizes ranging from 200KB to 1.5MB. Today, all the pictures I edited all came out large (2MB-4.5MB) via the action. This is crazy!
So I used a pic from today. I went through my editing process on the same pic twice, exactly the same way, only for one copy using the action to save/close the final image and for the other copy doing the steps of the action manually. The results came out as expected:

The "small" one, of course, being the one done manually, and the "large" one done through the action.
Thanks!
