I can upload some folders and some I can not do so. If I go to upload photos and videos I can browse several folders and some I can import and some I cannot.
I am confused.
If you are seeing a counter counting down in the bottom left corner then that is an indication that the photos have already been imported.
It is showing you the count of new/unimported photos (it will also exclude photos that are not supported by Lightroom)
You could uncheck the "Don't import suspected duplicates" checkbox on right side of the import panel but it is not recommended to do this.
You should instead check/search your catalog to see where you have already imported them.
