Bootstrap表单设计问题

Question

在我的bootstrap表单中，行之间有不寻常的间隙，尽管它们有相似的declarations.Also，选择框看起来比我在示例中看到的要大，

这就是问题所在

知道出什么问题了吗？

这是代码，

<div class="panel-body">
                <div class="tab-content">
                        <div id="content_obsinfo" class="tab-pane active">
                            <div class="col-sm-12">
                                <div class="row">
                                    <div class="panel-body form-horizontal form-padding">
                                        <div class="form-group">

                       </div>
        </div>
        </div>

当我检查第一行和第二行时，可以清楚地看到差异。

也许是项目中的另一个CSS？

col sm中的行？

行中的行？
