Betwen the coaching from Lazeeze and the advice of many others, I think I'm getting a handle on this. I've learned that stories can be submitted in multipke formats, not just the preferred text files, and I've received numerous tips and tricks from readers and other authors. NUMEROUS.
And while I still can't explain the odd Ös and other doodads, I do plan to try to clean up and repair the paragraph breaks on Back Trail after False Trail is posted. False Trail is ready to go as a txt file (at least as ready as I know how to make it), but Lazeeze is in correspondence with me and I asked his advice on a process that may affect my choice of file type. Even so, the txt file I have looks neat and clean to me, so I may just push the button. But not yet.
