turn off automatic spell-check for all documents

Libreoffice 6.0, Ubuntu 18.04. I do not want automatic spell-check and word completion on. Even when I uncheck them for a document and save the document, the next time I open the document it is on again. How do I permanently eliminate them? I am using my own style template and tried to remove automatic spell-check and word completion from that without success.

disable spell check - Tools|Options|Language settings|Writing Aids|Options - uncheck ‘check spelling as you type’

disable word completion - Tools|AutoCorrect|AutoCorrect Options|Word Completion - uncheck ‘Enable word completion’

Thanks, but… I’d done that and it also does not hold. Same for word completion. Setttings are not holding.
