[Plugin: Search Unleashed] Error with filter

I have three filters in setting page (#custom_field_template::custom_field_template_the_content # NextGEN_shortcodes::convert_shortcode and # WP_Embed::run_shortcode) that I cannot deselect. If I uncheck them and save, when I reload the filter page they are still checked. I’ve tried to uninstall and reinstall plugin, and tried to empty the values in wp_options table but nothing changes.

Someone can help me to resolve or tell me how disable the filters support in Search Unleashed?

If I leave selected NextGen filter, the indexing of search engine doesn’t work.
Tnx
