Are these iTunes encoded files? foobar2000 v1.1.6 introduced some Metadata Compatibiliy changes.What happens if you press shift + right-click -> Tagging -> Reload Info from files, as described in the mentioned WIKI article?
*UPDATE* Deleting the ITUNES COMPILATION field before deleting Various Artists from Album Artist field fixed it.

Instead I assume that your ALBUM ARTIST field has been empty and therefore fetched its content from the ITUNESCOMPILATION tag. If I am right the deletion of the ITUNESCOMPILATION tag would have been sufficient.If your ALBUM ARTIST tag would have had its own content, foobar2000 would have prioritized it over the ITUNESCOMPILATION tag.
foobar2000 links the iTunes ITUNESCOMPILATION tag to the ALBUM ARTIST tag. In case an ITUNESCOMPILATION tag is found in a file, foobar2000 treats it as if ALBUM ARTIST was set to "Various Artists". If an ALBUM ARTIST tag is found, ITUNESCOMPILATION will be ignored.
