The new version of K-stars released on July 25 continues having the same problem as the previous one. The Add-on installer implements the download and installation of catalogues and thereafter the program shows that the catalogues need to be installed again. The examples of these are the catalogues like Sharpless and Tycho 2. In some case like with Tycho 2, the main program shows that the catalogue is already installed while the add-on installer shows that there is a need to install the catalogue again.
