Duplicate class and give new name affects elements on other section

Hi guys.

I figured this must be a bug. I’ve never experienced this before. What happens is that hwen copy and paste a section, I want to give that second section a new name by pressing duplicate class, and write in a new name. But when I do, elements in another section change.
Can anyone help me out with this, please?

Here’s a link to a video where I show you what is going on:


Thank you for taking the time to report this, it definitely seems like odd behavior.

To help us locate and reproduce the issue on our end faster, we would appreciate if you can provide additional details:

  • Which date did you first notice the issue?

  • Please describe the steps taken leading up to the issue occurring

  • Upload screenshots/screencast videos displaying the issue

  • Please share your project’s Read-Only link AND live site’s Published link:

    • The read-only link is a special url generated in the Dashboard to allow others to view your project in the Webflow Designer. How to get your project’s read-only link?

    • The published link is the subdomain where you can view the live site with any custom code running. It is important to share this link, as custom code does not run in the Designer.

  • Please also let us know what browser version you’re using by visiting and copying the share link here:

Can you also please try the following:

  1. Try to see if the issue happens while being logged into Webflow using your browser’s Incognito Mode/Private Browsing with all plugins/extensions turned off, so that we can rule out a third-party conflict.

    How to start Incognito Mode/Private Browsing:

  2. If the issue still persists, open the browser’s developer console on the page where the issue occurs, take a screenshot, and upload it here as well.

    How to open the console:

Thanks in advance!

Hi @samliew

Thank you for your help. Here’s my information that you asked for:

  1. I noticed the issue 5 min before I wrote this post.

  2. The steps taken leading up to the issue is described in the origin post AND the video that I posted.

  3. Read only link (although I dislike sharing it on the forum before the project is finished) : and my published link:

  4. Video is provided in the origin post, don’t think you need a screen shot of it.

  5. My browser :

  6. I do have the same issue using incognito Mode/Private browsing.

  7. Do you want a screenshot of the console opened in designer mode or published page? Here’s from the designer:

Thanks again,

any progress with this issue @samliew ?

@Sven_Erik_Slattedale The staff is looking into it, and will provide an update when they are able to.

Just a quick question… May I keep working on the project while waiting on webflow staff to solve this issue? Or would it be best to just leave it as is for until the issue is fixed?


Thanks so much for posting about this! This is a known issue that affects some of our customers when duplicating class names.

I have added your site to the existing report of this issue and will post back here when I have more information. In the mean time, please continue editing your site as you normally would!
