@CharAznableLoNZ is the "Compilation" box checked in the tags? If it is, that song will go to the "Various Artists" folder no matter what the Album Artist field says. I've sometimes had an issue where the Compilation box will be inexplicably checked on albums where the artist is the same on every song--very annoying but thankfully pretty easy to fix.

@mncroc I think I see the issue--there are two different search boxes, and the minus sign works in one of them but not the other.

@Sharky-PI Actually, I just found a work-around for this! If you put quotes around the album name in the search bar, it will treat the dash as a literal dash and not as an exclude symbol.

@mncroc It's a minus sign. For example,

the beatles album:-"abbey road"

returns all songs by The Beatles (or that mention the Beatles in the tags) except the ones on Abbey Road.
The quotes are important if there's a space; otherwise, you'll get all songs that contain "the," "beatles," and "road" somewhere in the tags but don't have "abbey" in the album.

@CharAznableLoNZ when I right-click on songs in the sidebar, this menu comes up--maybe this will do the trick?

@Sharky-PI I think that's because the hyphen is used as a "minus", meaning "exclude this from the search results." For example, if you want to search for songs by The Band but exclude songs by The Band Perry, you can type "the band -perry".

I sometimes have a similar issue when I change the album art on a file that's currently playing.

Re: 2, the only think I can think of is maybe a couple of the songs are in a format Strawberry doesn't recognize or use file extensions it doesn't recognize? If it's the second one, it may be as simple as changing the end of the file name from .mpga to .mp3 or something like that. What format are the files in?

Re: 1, did you change the title of the song in the file tags, or just the name of the file? Apologies if you already know this, but if you have a file called Twinkle Twinkle Little Star.mp3, Strawberry won't assume that the song is called "Twinkle Twinkle Little Star"--you'll have to enter it manually or use the automatic tag completer.
If the files are already properly tagged but the tags aren't showing up in Strawberry... I'm stumped.

I transcoded some WAV files to AAC with the bitrate slider all the way up to 320kbps, but the resulting files had a bitrate of only 128kbps. Is there anything I can do to fix this?
