Sorry for long delay, but I could finally reproduce the issue.
Go to general CBSubs Settings, in Display tab, and Basket sub-tab, in group "Website payment information displayed inside the basket view", check setting "Columns displayed in basket on screen". It is probably set to "Custom" and has "Validity" column set. Setting the "Custom" back to "Default" removes that bizzare display.
I will now look into fixing this.
