Issues with the Moods/Music from LivePress

I have the excellent Moods/Music from the LivePress pack.
However I have several problems with it:
1: Once a post has been published, if I forgot to fill in the fields, it won’t take it as a modification.
2: I have dozen errors like this:
Warning: array_values(): The argument should be an array in /home/lily/public_html/nullsphere/wp-content/plugins/ljextras.phpon line 117
3: When I log in, I have a list of fields that takes about 5 minutes to load because it’s so long.
Does anyone have a solution to all this?
Thanks for the help
