KISS Upgrade 1.5.60 to 1.5.70

Having upgraded from version 1.5.60 to 1.5.70 the frontend of the advertiser comes up OK within my Joomla installation. In the backend (KISS Control Panel)it is shown, that indeed my current version is 1.5.70.
After either installation of the sample data or my own backup from prior to the upgrade and looking again, the same KISS Control Panel advises me that I am on 1.6.60 and that an upgrade to 1.5.70 is available.


Apparently something has gone wrong, but what?

Best Regards

Michael
