I have 5 tables I want to join

Invoices    Coletes   Clients  TagaCars  Incasaris
id 1           1         1         1         1 
               2
               3     

My query is: summing all the child coletes sum where coletes.invoice_id = invoices.id selecting the clients name selecting the tagacars model BUT is supposed to sum all the incasaris(which is basically encashment of an invoice), but when I do the sum in query it is doubling the sum for no reason

This is my query:

$invoices = Invoice::join('clients','clients.id','=','invoices.client_id')
->join('taga_cars','taga_cars.id','=','invoices.car_id')

->leftJoin('coletes','coletes.invoice_id','=','invoices.id')
->leftjoin('incasaris','invoices.id','=','i_plati_id')
->selectRaw(' 
sum(coletes.totaleuro) as total,
sum(coletes.totaleuro * invoices.i_rate) as totalabsolut,
sum(incasaris.i_totallei) as totalincasat,
clients.name, invoices.*, taga_cars.model')
->groupBy('invoices.id')
->orderBy('invoices.id')
->get();

The problem is only with "totalincasat"

Here you can see in my sql the ammount of i_totallei for one of my invoices

and here is my DD which is showing the doubled ammount for no reason

I want to mention that at the moment each invoice has only one incasaris belonging to each, and also, all incasaris summed combined would not be summed as 2000, it is simply doubling the result Does anyone have any suggestion? Is my first time I got to this "error" and I don't seem to understand how to fix it.
