In Xnview MP I disable some things in the 'file lists' option and restart the program and still XnView MP is recognizing such files extensions like exe, pdn, m4a I don't know what to do, I'm losing my head

In XnView win, there is a button in Tools>Options>Integration that simply auto-selects common formats to associate and like that I would like to see the same in 'File Lists' for when I view images in the 'Viewer' window. So a setting like 'Common Images formats strictly'
...I only use XnView to view image formats and not other formats (yet)
