The value zero is an exception. It needs -no- unit specification.

Sorry to hear that.

My counsel is to leave conforming CSS alone, if this is the only motive
for changing it - in the event that the W3C CSS "validator" (an
unfortunate choice of name - "checker" would be a safer choice) seems to
be disagreeing with the specification, first look for some other cause
(e.g wrong punctuation, presence of invisible bad character etc.), failing
which, feel free to report a bug to them.
No point in investing a lot of effort to overturn one's site which already
conforms to specification and isn't provoking some known bug in browsers
etc. - if they temporarily provoke a bug in a CSS syntax checker, then
don't panic, check the specs and be happy. The fact that some software
tools come from the W3C is no guarantee of perfection, you know.
