No discontinued message anymore

Hello! Since the last update to 1.4.0 (maybe also with an earlier version) I have the issue that the discontinued message is not visible anymore. I have these settings:

And this is how the page of the discontinued product looks like: https://www.kaerchercentersg.ch/shop/kaercher-akku-besen-kb-5/

Neither the user-defined message nor the standard message.

Do you have an idea how I can solve this?
