How to remove a check mark followed by input when the bootstrap form verifies that the content is entered correctly

bootstrap will follow a tick tag in the input box when the contents of the input box are filled correctly, but because I use input-group followed by a unit in some input boxes, there is a problem with the input. I would like to ask if there is any good solution

.

< div class= "form-group" >

                    <label class="col-lg-2 control-label"></label>
                    <div class="col-lg-4">
                        <div class="input-group">
                            <input type="text" class="form-control"  name="building" id="building">
                            <div class="input-group-addon"></div>
                        </div>
                    </div>
                    <label class="col-lg-2 control-label"></label>
                    <div class="col-lg-4">
                        <div class="input-group">
                            <input type="text" class="form-control" name="landarea" id="landarea">
                            <div class="input-group-addon"></div>
                        </div>
                    </div>
                    
                </div>

Hello, is your outside a simple < div class= "form-group" >?
there is no problem with the code you uploaded here. You need to change the code style of the check layer. I tested it online in Cainiao, and there is no problem. I hope I can help you clarify the point of the problem.
