How to avoid "Listing 1" on all code examples in org2blog export to wordpress?

[Steinar Bang]

Platform: GNU Emacs 26.3 (build 1, i686-w64-mingw32) of 2019-08-29
          Org mode version 9.1.9 (release_9.1.9-65-g5e4542 @ 
c:/ProgramFiles/emacs-26.3-i686/share/emacs/26.3/lisp/org/)
          Org2Blog 1.1.1

When I export to wordpress I get "Listing 1" on all text or code
examples in the wordpress blog, se e.g.
 
https://steinar.bang.priv.no/2019/11/30/rewriting-applications-to-use-pax-jdbc-config-and-liquibase/

Is there a way to lose the "Listing 1" text completely? 

Or failing that: is there a way to increment the number so that they
aren't all "1"?

Thanks!
