When you paste text inside of a RT element, it comes with many formatting attributes picked from its source, especially office docs, anything Rich Text actually.
To avoid issues like the one you’re facing, it’s better to paste raw text — text without formatting at all — in RT elements.
How to paste raw text in Rich Text elements:
- use cmd+shift+V instead of cmd+V. It pastes texts using the destination’s style, or paste raw text. Depends on the application. For Webflow, that’s pretty much working. Unless you paste your text when the cursor is on a title, then everything is a title
- paste your text in a pure text editors like Sublime, copy it again from there and paste it in Webflow. Beware, mac OS Text Editor is not a pure raw text editor at all, it does rich text too. (it can be but must be setuped)
