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!
