Quite new to Boostrap and can't figure out what could be triggering this line on my Create view and how to get rid of it.

The following are some of my opinions related to this field:

<h3 class="text-primary pl-3">Client Demographic Information</h3>
        <table class="table table-bordeless" style="width:100%">
            <tr>
                <td style="width: 30%">
                    <div class="form-group, mb-3">
                        <label asp-for="Incident.CaseType"></label>
                        <br />
                        @foreach (var item in Html.GetEnumSelectList<CaseType>())
                        {
                            <input type="radio" asp-for="Incident.CaseType" value="@item.Text"/>@item.Text
                        }
                    </div>
                </td>
                <td style="width: 30%">
                    <div class="mb-3">
                        <label asp-for="Incident.PIFirstName"></label>
                        <input asp-for="Incident.PIFirstName" class="form-control" />
                        <span asp-validation-for="Incident.PIFirstName" class="text-danger"></span>
                    </div>
                </td>
                <td style="width: 10%">
                    <div class="mb-3">
                        <label asp-for="Incident.PIMiddleInitial"></label>
                        <input asp-for="Incident.PIMiddleInitial" class="form-control" />
                        <span asp-validation-for="Incident.PIMiddleInitial" class="text-danger"></span>
                    </div>
                </td>
                <td style="width: 30%">
                    <div class="mb-3">
                        <label asp-for="Incident.PILastName"></label>
                        <input asp-for="Incident.PILastName" class="form-control" />
                        <span asp-validation-for="Incident.PILastName" class="text-danger"></span>
                    </div>
                </td>
            </tr>
        </table>
        <table class="table table-bordeless" style="width:100%">
            <tr>
                <td style="width: 40%">
                    <div class="mb-3">
                        <label asp-for="Incident.PIAddressCity"></label>
                        <select asp-for="Incident.PIAddressCity" id="Select1" class="form-select" asp-items="@(new SelectList(Model.DisplayCityData.OrderBy(x => x.CityName),"CityName", "CityName"))"><option value="" selected disabled>---Select Residence City---</option></select>
                    </div>
                </td>

Hope someone can help. Thanks!
