When I try to reorder sub-categories within a category, I get a strange error popup window.

TypeError: Cannot read properties of null (reading 'children') at ix (https://wa-js-cdn.nyc3.cdn.digitaloceanspaces.com/assets/prodromos/alchemist/assets/index-Bqixe2lX:303:231055) at https://wa-js-cdn.nyc3.cdn.digitaloceanspaces.com/assets/prodromos/alchemist/assets/index-Bqixe2lX:361:111588 at Object.us [as useMemo] (https://wa-js-cdn.nyc3.cdn.digitaloceanspaces.com/assets/prodromos/alchemist/assets/vendor-react-euclid-BTjiy5x8:6:21295) at e.useMemo (https://wa-js-cdn.nyc3.cdn.digitaloceanspaces.com/assets/prodromos/alchemist/assets/vendor-react-euclid-BTjiy5x8:1:6266) at https://wa-js-cdn.nyc3.cdn.digitaloceanspaces.com/assets/prodromos/alchemist/assets/index-Bqixe2lX:361:111245 at Lo (https://wa-js-cdn.nyc3.cdn.digitaloceanspaces.com/assets/prodromos/alchemist/assets/vendor-react-euclid-BTjiy5x8:6:16918) at qs (https://wa-js-cdn.nyc3.cdn.digitaloceanspaces.com/assets/prodromos/alchemist/assets/vendor-react-euclid-BTjiy5x8:8:3141) at Ws (https://wa-js-cdn.nyc3.cdn.digitaloceanspaces.com/assets/prodromos/alchemist/assets/vendor-react-euclid-BTjiy5x8:8:2353) at $l (https://wa-js-cdn.nyc3.cdn.digitaloceanspaces.com/assets/prodromos/alchemist/assets/vendor-react-euclid-BTjiy5x8:8:47214) at Hl (https://wa-js-cdn.nyc3.cdn.digitaloceanspaces.com/assets/prodromos/alchemist/assets/vendor-react-euclid-BTjiy5x8:8:39635)
