I don't know anything specific to the H10 as I don't own one.
I'm guessing that your config.cfg might be corrupted as well as you playlist control file, try this:
get everything set properly, just as you like it then save settings to a file
(menu > manage settings > save .cfg file )
Then shut down, delete config.cfg from /.rockbox then rename your created config (presumably config01.cfg) to config.cfg and put it in /.rockbox (if it isn't already)
If this loads properly, then your original config.cfg file was corrupt (and so, your playlist control is probably too). So just delete .rockbox (except for the appropriate folders for theme data) and extract a fresh build. If your settings still don't load I can't think of what is wrong.
hope this helps you out
