it's not about typing in the description field, it's about using the "Text Replacement" function in Macos, where you can automatically substitute a text you type by a saved text (usually a short abbreviated text replaced by a much longer text)

We added a Rich Text Editor lately to the offer form which might cause the issue.
I now have added a Legacy Mode button to return to the web conform standard form. Maybe that fixes the issue?
