None of the textBox control on page is selectable

I have few pages, all works great but one page where it has almost everything same as other pages but I can't select the text typed on textBox control on this page. Is there anything that is preventing me from doing that? as I said, all CSS/Styles etc are same as other pages and this particular one is not working.

Sample of that page is:
< RadzenCard class="shadow bg-white rounded mb-2" >
< RadzenTemplateForm TItem="TargetingSystemAudience" Data="@currentAud" InvalidSubmit="@OnInvalidSubmit" Style="width:100%" >
< div class="row" style="margin-bottom:5px;margin-top:10px" >
< div class="col-5 mb-2 mt-2 p-1 shadow bg-white rounded" >
< RadzenFieldset Text="General Info" AllowCollapse="true" >
< div class="row" style="margin-bottom:10px" >
< div class="col-9" style="margin-bottom:5px;float:left" >
< RadzenAutoComplete Data="@listOfAudience"
TextProperty="AudienceName"
@bind-Value="searchTextTmp"
Placeholder="Enter audience name..."
FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive"
Style="width:100%" / >
< / div >
< div class="col-3" style="text-align: right;float:right" >
< RadzenButton Text="Search"
Click="@SearchAudience"
class="btn btn-light"
Style="width:100%;padding:0;"
data-toggle="tooltip"
title="Search all versions of this audience.." / >
< / div >
< / div >

                    < div class="row" style="margin-bottom:10px;" >
                        < div class="col-4" style="margin-bottom:5px; " >
                            < label>Audience Name* < / label >
                        < /div >
                        < div class="col-8" style="margin-bottom:5px" >
                            < RadzenTextBox Name="txtAudName"
                                           Placeholder="Enter audience name..."
                                           @bind-Value="currentAud.AudienceName"
                                           Style="width:100%" / >
                            < RadzenRequiredValidator Component="txtAudName" Text="Audience name is required" Style="position:relative"  / >
                        < /div>
                    < /div>

Please format your code ...

I have updated and re-formatted as much I could.
As I said, this page has almost exactly what other page has. One works just fine and other does not.

There's probably another div on top of your textboxes.

This issue for for all the text boxes (including AutoComplete control) on this page, not this particular one. I can not select any of the texts that is typed on ANY of the text boxes. Here is another text box as example:

< div class="row mb-1" >
< div class="col-md-2 float-left" style="margin-top:10px" >
< label >ADO Items< /label >
< / div >
< div class="col-md-4 float-left ">
< RadzenTextBox Name="ADO" Placeholder="Enter ADO number & save..." @bind-Value="currentAdoNumber" Style="width:100%" />
< / div >

Would be great if anybody can have any insight here. Or anybody else experiencing same issue?
