You can't change anything in the extension to avoid this. This is 
tdf#120363 [1], and is fixed in LibreOffice 6.2.

There are other cases when similar warnings appear; see e.g. [2] which 
is about warning in script organizer dialog, fixed in 6.3.1. If you come 
across such problems in current releases, please file a bug and CC me. 
Thanks.
