Question about product attributes inaccessible

[Konst7]

Hello. In setting off the display attributes inaccessible goods and when, for example, ends with the size of any of the goods, on the product page appears, "This version is not available. Please choose another." (although there is an attribute of the product is no longer on the page). As I understand it, the inscription appears when the end of the first attribute of the product. For example there are 3 sizes of clothes - S, M, L. Ends size S - attribute on the product page does not (as disabled in the settings), but there is this inscription. If the item ends with M - that everything is OK, no inscriptions.

How do I fix this bug? In order not to appear this strange inscription. Thank you.
