Transforming to lowercase upon saving

Hello,

I created a table with the name and information of different clubs.
When I go into edit mode of that specific table and I change to name of a club from "leuven" to "Leuven" and click save it changes automatically to "leuven".
How can I prevent that from happening? Because when I sorted my table from the front end, "leuven" comes after "Zaventem" for example and that's not what I want.

Thank you,
Greetings

Is the field with the Clubname the alias field of your Table?

Hello,

sorry for my late reply (I was on holiday). Yes the it is the alias.
