Asset files does not exist ?

Hello, i have troubles with asset files. After i create my assets , close/open project, their names looks different then normal names ( they are not same names with i created). Also when i debug project they are giving warnings but works, but i face with errors when archiving and i believe it is connected with this, when i check the location with file explorer i can see them. Another interesting point is that sometimes i saw 2 picture with same resolution. One of them endings "1" with its name. Here some screen shots about what i am saying. I also try to delete some unnecessary ( maybe old) lines from csproj file, for avoid try to loading images which is not exist but it still same
