Think black border line on Markdown Video Blocks

Hi all,

I am having issues with some thin black lines suddenly appearing on my site where I have used a markdown box to input a video using this code:

<video playsinline loop muted autoplay width="100%">
  <source src="/s/database-management.mp4" type="video/mp4" media="all and (max-width: 640px)">
  <source src="/s/database-management.mp4" type="video/webm" media="all and (max-width: 640px)">
  <source src="/s/database-management" type="video/mp4">
  <source src="/s/database-management" type="video/webm">
</video>

An example page is: https://www.ncs-london.com/data-services-home/#emergencydatabasesupport, you will see the first section 'Emergency Database Support' shows the line.  Another example page is: https://www.ncs-london.com/managed-services-home/#databaseadministration, again the first section 'Database Adminstration'

This is a new occurrence.

Many thanks as always! 

(p.s. for some reason when I take a screenshot the black line is not on the image?)

Which line do you mean?  I can not see it. Can you share some screenshots?

This is strange, as I can see them logged into SQS, plus a direct link to the site on Chrome and on Edge but when I screengrab a shot they do not appear ??

which line? can you highlight that line in image?

I have had to take a photo with my camera as it does not show up with a screen grab. You can see the black border  code box line on the Managed Services page under the video.
