List Numbers Showing Incorrectly

Hello, While updating one of my lists, I clicked "save list order" an error ocurred, and the list numbers went crazy. For example, my list now has 4 number "1". Every time I try to correct it, it stays the same :( The list: https://www.imdb.com/list/ls529365510/ (it's a private list) Can you help me? Thank you!
