I've recently created a campaign on here and a few homebrew items.  Each time I hit save an embedded frame is added to the description.  I've copy and paste the information from discord but also on one item I typed it in but a frame still applied after I saved it. I keep editing it and removing the frame and link but after I hit save it keeps coming back.  Why is this happening and how do I stop it?  

It happened to this post too btw

Those links are invalid. Can you post an image of what you're talking about?

But as a guess, do you have Beyond20 enabled? If so, turn it off, as it has a tendency of adding extraneous tags in posts and homebrew.

None of your links are working, but at the top of the description field you see those little grey buttons? Hit the one with this symbol:

That will let you see the html source code and then delete any coding that doesn’t look like this:

Thanks, I tried that they still came back.  To be clear, I don't want the links to work or to be there.  I'm not trying to add any files or links.  They just keep appearing and I don't know how or why. 

Edited: It worked actually I found the button, Thank you.

Now my question is why is this happening every time I post. 

Are you using any browser extensions? Or... if something keeps embedding links to videos, you might have picked up something.

Yeah, it seems like you got a virus.

This appears to be an issue with your local machine modifying your site inputs, rather than an issue with D&D Beyond itself.

I'm having the same issue which is making the entire homebrew process a pain, so I'm guessing it isn't a local machine thing but a site thing or a browser thing.
