Hello Lauren, to me the container of your smaller Aloe is still too big, and media seems too wet. Sometimes manifestation of over and underwatering looks the same on the leaves. I would let that plant dry out a bit more, and position in more light. Have you checked the condition of the roots below?
Aloe really likes being grown outdoors with more warmth and light, but when grown indoors and temps go lower in Fall and light duration goes shorter, then you have to adjust the watering intervals much longer. If you cannot repot smaller, try to add more grittiness to your media, add more pumice or perlite to it, so your plant does not sit in too much moisture.
