How to remove unused entries on page head

I am no longer using summer notes, medium notes or backgroundvideo. But I could not get rid of below given entries from my layout page. Any idea why they reappear and how to remove?

 <script src="/dmxAppConnect/dmxSummernote/dmxSummernote.js" defer=""></script>
<link rel="stylesheet" href="/dmxAppConnect/dmxMediumEditor/dmxMediumEditor.css" />
<script src="/dmxAppConnect/dmxMediumEditor/dmxMediumEditor.js" defer=""></script>
<link rel="stylesheet" href="/dmxAppConnect/dmxMediumEditor/medium-editor.css" />
<script src="/dmxAppConnect/dmxMediumEditor/medium-editor.js" defer=""></script>
<link rel="stylesheet" href="/dmxAppConnect/dmxMediumEditor/themes/default.css" />
<script src="/dmxAppConnect/dmxBackgroundVideo/dmxBackgroundVideo.js" defer=""></script>

Hi.
Check the comment at the top of your content pages. If they have references to these components, the supporting css & js files will get added to layout page on each save of the content page.

sid, it is following component on all pages;

"Wappler include head-page=“layouts/main” fontawesome_5=“cdn” bootstrap5=“local” is=“dmx-app” id=“login” appConnect=“local”

However, I did move some of the comments to the top because they were at the bottom. Then I deleted the unwanted references from the DOM it it did not reappear.

thanks for the tip
