Here is the solution, remove it's 'module' completely altogether from the system without any tweaking:

1. Go to the command line, where Magento is.

2. run:

php bin/magento module:uninstall Magento_LayeredNavigation

3. Confirm (Yes, Yes,... )

4. Remove the old cache/and generated content:

rm -rf var/cache/* pub/static/frontend generated/code/*

5. Re-Index:

php bin/magento index:reindex

6. Clear the cache:

php bin/magento index:reindex

4. If needed, clear the cache and refresh.

if you miss it, and want it back, or if removing causes problems, then re-enable it using:

php bin/magento module:enable Magento_LayeredNavigation

I hope this helps.
