Mod Pagespeed部分应用。 仅合并少量JS文件和其余部分不会合并

Question

I have mod_pagespeed installed for apache and for 1 website I have enabled it using .htaccess. Below is the .htaccess code :

<IfModule pagespeed_module>
ModPagespeed on
ModPagespeedEnableFilters combine_javascript
ModPagespeedEnableFilters collapse_whitespace,elide_attributes
</IfModule>

Though combine JS is written. It doesn't combine all JS into 1 file and show it in 1 single script tag. Below is the script loaded after pagespeed is applied:

<script src="https://abcd.com/assets/js/jquery.min.js,qv=45.3.68.pagespeed.jm.g-Rqg9FLCg.js" type="application/javascript"></script>    <!-- jQuery library -->
<script type='application/javascript' src="https://abcd.com/assets/js/jquery-ui.min.js,qv=45.3.68.pagespeed.jm.2Zsi-Z0kKK.js"></script>
<!--<script type='application/javascript' src='//apis.google.com/js/client.js'></script>-->
<script src="https://abcd.com/assets/js/vvv.min.js,qv=45.3.68.pagespeed.jm.OArlW9Bphb.js" type="application/javascript"></script>

<script>eval(mod_pagespeed_dGnDIMpPX7);</script>
<script src="https://abcd.com/assets/js/jquery.history.min.js+jquery.mCustomScrollbar.concat.min.js.pagespeed.jc.kZ5nzlQvQy.js"></script><script>eval(mod_pagespeed_RoTwDjZDVk);</script>
<script>eval(mod_pagespeed_V826YrUaHB);</script>
<!--    Jplayer   -->

Here is the script without pagespeed implementation.

<script src="https://abcd.com/assets/js/jquery.min.js?v=45.3.68" type="application/javascript"></script>    <!-- jQuery library -->
<script type='application/javascript' src="https://abcd.com/assets/js/jquery-ui.min.js?v=45.3.68"></script>
<!--<script type='application/javascript' src='//apis.google.com/js/client.js'></script>-->
<script src="https://abcd.com/assets/js/vvv.min.js?v=45.3.68" type="application/javascript"></script>
<script src="https://abcd.com/assets/allcityname.js?v=45.3.68" type="application/javascript"></script>
<script src="https://abcd.com/assets/js/main.min.js?v=45.3.68" type="application/javascript"></script>
<script src="https://abcd.com/assets/js/resize.min.js?v=45.3.68" type="application/javascript"></script>
<script type="application/javascript"  src="https://abcd.com/assets/slick/slick.min.js?v=45.3.68"></script>
<script type="application/javascript"  src="https://abcd.com/assets/js/bootstrap.min.js?v=45.3.68"></script>
<script type="application/javascript"  src="https://abcd.com/assets/js/jquery.lazyload.min.js?v=45.3.68"></script>
<script type="application/javascript" src="https://abcd.com/assets/js/jquery.history.min.js"></script>
<script type='application/javascript' src="https://abcd.com/assets/js/jquery.mCustomScrollbar.concat.min.js"></script>
<!--    Jplayer   -->
<script type="application/javascript" src="https://abcd.com/assets/js/jquery.jplayer.min.js"></script>
<script type="application/javascript" src="https://abcd.com/assets/js/jplayer.playlist.min.js"></script>

What is going wrong ?
