Extra scores

When I launch the musescore program, there are a bunch of extra blank scores in the start center that I never created labeled "scm22360" or "scU10924". There are also extra copies of scores that I am/was working on. This is a pain and causes me to have to search through a bunch of blank or unneeded scores to find the one I want, and sometimes two of them look exactly the same so I don't know which one I was actually working on. I do not know how to get rid of them either because they don't actually show up in my files, and don't do anything when I right click. I think what's causing this is that I sometimes shut down my computer and forget to save, and when I open the program back up it says that it closed unexpectedly and asks if I want to restore the version. When I say yes, for some reason I think it copies the original file and a new file. I don't understand how this works or if is even this that is causing it, but nonetheless I have no idea how to remove them. Does anyone else have this problem? Thanks.
