Thank you for posting and for bringing this to our attention! This definitely sounds like strange behavior.
I attempted to reproduce the behavior in a new site and with your site, but was unable to.
When did it start occurring? Is it occurring with more than this site?
Can you please try the following:
(1) Try to reproduce the error while being logged into Webflow using Incognito mode with browser extensions turned off: https://support.google.com/chrome/answer/95464?hl=en
(2) If the problem persists, please take a screenshot of your Console and send it to me: https://developer.chrome.com/devtools/docs/console
Thanks in advance and I'll be standing by for your response!
