Spell check issues - Writer


Amateur alert!

I have been through some answers provided to others but have failed to resolve my problem.Spell check claims that there are no mistakes when there clearly are.

OS is win 10 and using LO version

Ultimately I would like to set language to English-Australia (have downloaded and installed the language language pack to zero effect). I could get away with using Eng-uk if I had to.

I have followed some very clear and well laid out answers for previous versions and got nowhere. Please help.
