Availability image or text not displaying

[tzic]

Hello I run into this with the latest update 2.0.20b Availability image or text is not displayed below add to cart button. http://www.ahealthcare.gr/%CE%BA%CE%B1%CF%84%CE%B1%CE%BA%CE%BB%CE%B9%CF%83%CE%B5%CE%B9%CF%82/%CE%B1%CE%B5%CF%81%CF%8C%CF%83%CF%84%CF%81%CF%89%CE%BC%CE%B1-%CE%BA%CE%B1%CF%84%CE%B1%CE%BA%CE%BB%CE%AF%CF%83%CE%B5%CF%89%CE%BD It only displays if the product has child products *confused*

Any thoughts on this issue?

PS Something must be wrong with availability date under product status. Cannot change or delete that date
PS2 here's a link to a product with children http://www.ahealthcare.gr/eshop/%CF%80%CF%81%CE%BF%CE%B9%CE%BF%CE%BD%CF%84%CE%B1/%CE%B5%CF%80%CE%B9%CE%B8%CE%B5%CE%BC%CE%B1%CF%84%CE%B1-hartmann/%CE%B5%CF%80%CE%B9%CE%B8%CE%B5%CE%BC%CE%B1-permafoam-round-6cm-detail
