Crash when deleting indexes in a certain order

[hanks42]

When I have multiple indexes in order (1, 2, 3) if I use the UI to delete them and delete number 2 then number 3 the app will crash. It will not if I delete number 3 first then 2.

Here for example delete category_name_1 first then try to delete category_name_text
