Card Designer Bug?

In the editor view, I see the left side (which is correct and how I typed it in the title field).

But in the preview and browser, it looks like the right side.
What’s this strange behaviour?

Looks like a character limit in both cases, but I can’t tell what’s happening. can you send a link or a project file so I can determine the cause for you.

Direct message it to me here in the forum is fine.
