This problem is due to biblatex-apa's (apa.bbx's) apaauthor name format; you might want to notify the author of this small bug.
The string and others in the author list sets ifmorenames to true. apaauthor checks for this case whenever a name is printed, not just at the very end of the list; consequently it prints the andothers string ("et al.") after each name.
The fix is to add the following lines to your preamble.
\DeclareNameFormat{apaauthor}{%
\ifthenelse{\value{listcount}=\maxprtauth\AND\value{listcount}<\value{listtotal}}
{\addcomma\addspace\ldots\addspace}
{\ifthenelse{\value{listcount}>\maxprtauth\AND\value{listcount}<\value{listtotal}}
{}
{\ifthenelse{\iffieldequalstr{doubtfulauthor}{true}}
{\mkbibbrackets{\usebibmacro{name:apa:last-first}{#1}{#3}{#4}{#5}{#7}?}}
{\usebibmacro{name:apa:last-first}{#1}{#3}{#4}{#5}{#7}}}}%
\ifthenelse{\value{listcount}=\value{listtotal}}% this test is new
{\ifmorenames{\andothersdelim\bibstring{andothers}}{}}{}}

then yields
Update 2013-10: This has been corrected in biblatex-apa version 6.4 according to a comment below the question from user PLK.
As Bernard says, it works except for the bits which don't work due to non-existent types, unrecognised fields or missing bibliography entries.
Rather than webpage, you may want online. Rather than lastchecked, you probably want urldate:

The
biblatex-mlastyles has not been updated since 2013. In the past the style worked more or less smoothly (ignoring the odd rough edge here and there), but some functions were not set up or implemented leaving you with empty citations in some cases (see URL in footcite mla for example).The recent changes to
biblatex's name format introduced in version 3.3 (see Biblatex 3.3 name formatting) have now made the style pretty much unusable.You should consider ditching
biblatex-mlafor a more up-to-date and maintained style. If you absolutely have to usebiblatex-mlaand don't needbiblatex's Biber only features, you can use the BibTeX backend instead of Biber, because the changes to the name format were not applied to the BibTeX backend.The following MWE thus works
