And yes I know it doesn’t have the upside down ketchup cup but I like it better like this!

Hey plant community! I need some help uncovering the problem of why my Christmas cactus is shedding leaves as well as this brownish yellowish collar that has appeared on it! I bought this plant about 5 months ago and I have been watering it once a week ever since then. Been keeping it in that spot for a while and it’s been doing fine. But recently the past month it’s started to shed leaves and grow these yellow brownish marks on it! The roots look fine (in the photos I had just watered and sprayed the plant with water) and I just can’t figure what the problem could be… can I get some help from the plant professionals out there?
