Setting an ivoice as "Paid" the "Paid" amount stay to 0

By setting the status of an invoice as “PAID”, the amount under “Paid” should not be equal to the total of the invoice? It seems weird to stay at zero.
Maybe I’m wrong to interpret? Or is it a bug?

Thank you all !

Did you entered a payment for the invoice?
If yes: it’s a bug.
If not: no. Changing the status will not lead to different amounts.

Oh sorry. now it works.
I do not realized that the two things was correlated.
Thank you very much for the precious help.
