fileupload进度栏放错了撇号

Question

在上图中，上传第二个文件时，它显示了第一个文件上传的进度条

<h:panelGroup>
    <h:outputText id="keyupload" value="Key file(extension should be .key)"/>
    <p:fileUpload id="keyfileUpload" label="Upload KeyFile" fileUploadListener="#{exampleBean.keyFileUpload}" mode="advanced" auto="true" allowTypes="/(\.|\/)(crt|key)$/" />
</h:panelGroup>

<p:separator id="separator1"/>

<h:panelGroup>
    <h:outputText id="certupload" value="Certificate and Key file(extension should be .crt)"/>
    <p:fileUpload id="crtUpload" label="Upload File" fileUploadListener="#{exampleBean.crtFileUpload}" mode="advanced" auto="true" allowTypes="/(\.|\/)(crt|key)$/" />
</h:panelGroup>

如何保持正确的方式，任何人都可以帮忙
