Issue with Ajax Unobtrusive form submitting twice sometimes in .net core razor

Question

Sometimes form submit multiple times in razor page. I am using version 3.2.6 of unobrustive ajax. I double checked the viewpagesource to make sure only one unobrustive ajax library is there. There are two forms one after another 1st form

 <form method="post" id="loginForm" data-ajax="true" data-ajax- 
method="post" data-ajax-success="success" data-ajax-failure="failure" 
data-ajax-loading="#spinner">
                        <div class="row">
                            <div class="col-md-12">
                                <div class="form-check mb-2 mt-3 form-check-inline">
                                    <input class="form-check-input" type="radio" value="C" id="customradio1" checked name="Input.UserType" />
                                    <label class="form-check-label" for="customradio1">Complainant  <strong class="text-danger" title="A Complainant is a registered company who can blacklist an individual or a company for doing an un ethical act." data-plugin="tippy" data-tippy-placement="top">(?)</strong></label>
                                </div>

                                <div class="form-check mb-2 form-check- 
             inline">
