How not to Ignore Values Filtered by Another Table

I have existing report and now I need to and new table without changing old tables.

Here is the peace of the model:

New Table is connected by compozite key company+contract.

Sometimes rows in New table have ContractID = 0, but ManyToMany table does not.

I need to calculate sum of Money column including rows with ContractID = 0.

Expected:

Company

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUfJLzE01VIrViVYygvKMlGJjAQ==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Company ID" = _t, #"Company Name" = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Company ID", Int64.Type}, {"Company Name", type text}})
in
#"Changed Type"

Contracts

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjQ0VNJRcjZUitWJVjIyMgJxjMAcY2NjEMdYKTYWAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Contract ID" = _t, #"Contract Name" = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Contract ID", Int64.Type}, {"Contract Name", type text}})
in
#"Changed Type"

ManyToMany

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTI0NFSK1YlWMgKyjYyMwGxDNLaxsbFSbCwA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Company ID" = _t, #"Contract ID" = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Company ID", Int64.Type}, {"Contract ID", Int64.Type}})
in
#"Changed Type"

New

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUTI0BJMGBkqxOhARIyMjIGmKJGJsbAwSRxIxAKtQio0FAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Company ID" = _t, #"Contract ID" = _t, Money = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Company ID", Int64.Type}, {"Contract ID", Int64.Type}, {"Money", Int64.Type}})
in
#"Changed Type"
