LINQ query with Where Clause when join multiple tables in ASP.Net MVC

I am using below linq, in which date parameter is not working properly.

I am facing issue, that when i filter data on date between, then relevant data does not come accordingly date.

If i remove join and then filter data on date between, then relevant data get display accordingly date.

View

@model IEnumerable<ERP_APP.Models.BBDetailView>
@{

}

<div class="card">
    <div class="card-header">
        <div class="text-sm">
