Yes it's possible to edit which titles are in a list that way, but this error prevents the list name and visibility from being changed. As far as I can tell, there's no workaround for those. Other than creating a brand new list and starting from scratch, which is too much of a hassle.
When editing certain MDLists, clicking Update List does nothing except show a permanent loading icon. Console log shows "TypeError: Cannot read properties of undefined (reading 'data')"
