So after few hours of trying everything yesterday where I checked other forum posts and nothing worked I gave up. But this morning I deleted both rows and added them again and now it all works, so I am not sure why same thing did not work yesterday as I tried it then too but I can say that this is sorted now, my atomic number is decimal and points are numeric and did not use any varchar options for those three.
