I think you are hitting this, from the rsync manpage:

       rsync finds the files to send.  If  a  pattern  excludes  a
       particular parent directory, it can render a deeper include
       pattern ineffectual because rsync did not  descend  through
       that  excluded  section of the hierarchy.  This is particu‐
       larly important  when  using  a  trailing  ‘*’  rule.   For
       instance, this won’t work:

              + /some/path/this-file-will-not-be-found
              + /file-is-included
              - *

       This  fails because the parent directory “some” is excluded
       by the ‘*’ rule, so rsync never visits any of the files  in
       the  “some” or “some/path” directories.  One solution is to
       ask for all directories in the hierarchy to be included  by
       using a single rule: “+ */” (put it somewhere before the “-
       *” rule), and perhaps use  the  --prune-empty-dirs  option.
       Another  solution  is to add specific include rules for all
       the parent dirs that need to  be  visited.   For  instance,
       this set of rules works fine:

              + /some/
              + /some/path/
              + /some/path/this-file-is-found
              + /file-also-included
              - *
Best regards,
