All the videos are not shown when using Group by folder option in group videos. Many folders are appearing empty with no media files in them. But, everything works in the disabled option of Group videos.
I must continue using previous version for lack of capacity to group by same first 6 letters. Otherwise seems to work fine (not casting or using it for music).
When videos are grouped, single videos cannot be deleted unless returning to ungrouped list. Also took a while to discover Grouping vids was available under the sort option.
