It looks like you might have copied and pasted this.
If you remove this section and re-add as paragraph (not via copy and paste), it should look as expected!
Here are step by step instructions:
Delete the section that's not displaying correctly.
Instead of pasting directly from another source (like Google Docs or Word), retype the content manually into the editor or paste it into a plain text editor (like Notepad or TextEdit) first to strip formatting.
Then copy from there and paste into Website Editor.
