can not delete savings why?tride different ways saves will not delete .they apper to be deleted ,then i log back on and all saves are back,why.

Maybe they're recreated from the cloud saves?

Probably what phaolo said. Turn off cloud savings in Galaxy (more->settings->uncheck sync local saves with GOG Galaxy Cloud), launch the game, delete the savegame, quit game, restart the game and see if it worked.
