Red Maranta is yellowing and crispy-ing up?

I recently got this red maranta and let her acclimate for about 3 weeks before changing her soil which was staying too moist. I literally just changed the soil she was in and put her back into the same pot I bought her in. It’s been about a week now and she just keeps getting more and more crispy, not nearly as full as when I first got her. Only water her when her soil is almost dry. She sits by a south facing window with shade (second pic) and I keep a humidifier running near her. She seemed to be doing alright but I figured if I kept her in the soil she was in she would eventually rot.

Is she just shocked from the repot?
