Hello jbmfg! To me your plant looks like a Dracaena Janet Craig. At times, plants do drop older lower leaves first. Since you said you just recently repotted it, maybe there was some root disturbance it is reacting to, and if you repositioned the plant, it maybe adjusting to it as well.
Just be careful with watering, don't make them too soggy. Over and underwatering manifests the same on the leaves.
It is a low light plant, so make sure it does not get too much direct sun.
