It does that because, as mentioned, the Section names in an INI file have []'s around them. If you have []'s around an item name, then as far as the INI is concerned, the item becomes a topic instead, which is obviously undesirable. The best thing to do is either use an alias as mentioned or else decide *why* you need []'s in the item name and decide if there's some other character(s) that you can use instead such as ()'s or {}'s.
