Sum query doubles when joining three tables in Laravel - mysql

Question

I'm sending data to chartist.js using Laravel controller. When I try to join three tables together to sum the values, the output is essentially doubled when I join the third table.
The following query gets the data I need however doesn't sum them accurately
$chart_stats = Transactions::join('customers', 'customers.id', '=', 'transactions.customer_id')
->join('orders', 'orders.customer_id', '=', 'transactions.customer_id')
->distinct()
->select('customers.region', 'transactions.deposit', 'transactions.purchase_total', 'transactions.finance_amount_paid', 'orders.gov_funding_amount')
->whereIn('customers.region', $selected_regions)
->where('transactions.created_at', '>', $from)
->where('transactions.created_at', '<', $to)
->select(
DB::raw('customers.region as region' ),
DB::raw('sum(transactions.deposit) as deposits'),
DB::raw('sum(transactions.purchase_total) as sums'),
DB::raw('sum(transactions.finance_amount_paid) as finance_paid'),
DB::raw('sum(transactions.deposit+transactions.finance_amount_paid) as total_paid'),
DB::raw('sum(orders.gov_funding_amount) as funding')
)
->groupBy('customers.region')
->orderBy('sums', 'asc')
->get();
This will output the following in an array:
#original: array:6 [▼
"region" => "Region 1"
"deposits" => "5025.40"
"sums" => "52875.00"
"finance_amount_paid" => "0.00"
"total_paid" => "5025.40"
"funding" => "9228.00"
It should be:
#original: array:6 [▼
"region" => "Region 1"
"deposits" => "1706.00"
"sums" => "21271.00"
"finance_amount_paid" => "0.00"
"total_paid" => "1706.40"
"funding" => "3396.00"

I was going to give this as a comment but it would be better as a answer. It's a proposition and I could be wrong. There are 2 possible answers.
Change these lines:
->where('transactions.created_at', '>', $from)
->where('transactions.created_at', '<', $to)
To either:
->whereBetween('transaction.created_at, $from, $to)
Or edit: type, arrays into arrays, corrected:
->where([['transactions.created_at', '>', $from], ['transactions.created_at', '<', $to]])
Methink it is possible, if both conditions are true, the row is selected twice. The distinct() may not do what it is intended to do. You could also try a closure:
->where(function ($query) {
$query->where('transactions.created_at', '>', $from)
->where('transactions.created_at', '<', $to)
->distinct();
})
