None of this is really a surprise to me. When I was putting together the look of the site, I assumed everyone would use Getaway Green. Some other styles have certain mods but are missing others and all sorts of unpredictable things can occur. The ReelViews logo, for example, is hardcoded into the Getaway Green template but isn't in anything else. Some of the individual forum pages are set up to use whatever the default is; others are hardcoded to use Getaway Green. There are actually rational reasons for some of these seemingly irrational occurrences, but it would be rather long and tedious to explain them all.
Probably the best thing for me to do would be to wipe everything except Getaway Green, since it's really the only style that's supported. The two standards that come with the phpBB package are there because they come with it (duh). The eTech Green is something I played with, but I decided I prefer the look of Getaway Green. You can still use the others, but there will be issues.
