Since I updated OSMap to their new refactored version 4.0.x the settings in plg_osmap_com_easyblog_5_5.0.3_free.zip configuration no longer have any affect on what's included in the site map HTML or XML pages. They made some pretty big changes to OSMap in version 4, so maybe this is something you should look into.
See screenshots for my plugin settings and what actually shows on the site map. Plugin is configured to show 500 blog posts, but it only shows 20. I have blogger posts set to Never Show, but the map shows up to 5 for each author. I disabled those duplicate pages through OSMap's new feature to edit links. Also it only shows 10 bloggers and I set plugin to show 500. There's only 14, but it still limits the list to 10.
