How to add invoice fields to order list view

[LucasV]

Hi,

I would like to add some invoice fields to the order list view of Prestashop. 
After searching online, I came across these tutorials / forum articles:

https://mypresta.eu/developer/add-date-of-invoice-to-list-of-orders.html

Both of these are an answer to my question, but they don't seem to work for me.
I tried clearing my cache but nothing changes in the order list view..

Any ideas?
I do already have an extra field in this view made by a module of my payment service provider.

Hi @ndiaga

I have many orders where the invoice is created.

or does it only appear after new ones and not for old ones?

Hi!

The invoices are visible, I just want to add extra fields in the order view:

- invoice creation date
- invoice number
 

I tried the above mentioned tutorials who tell it should be visible immediately.

But  you  already  have  the  order  reference   and  the  order  placed  date.

Hi! Yes, I do but I also need the invoice date to have an overview of invoices that are due and these fields don't help for that.
