Problems with uploading files,duplicates and more

Hi, I am self hosting and running the latest production version.
I am trying to setup the website part.
Here are some issues I ran into:
*I cannot upload all my folder/files. The file manager only accepts files.
*Tried the import-ZIP but my 1.4GB file stays at 1%.
*When I upload anything bigger than 2-3 MB the upload finishes but nothing actually happens, no file gets added.
*When I use an image from library it gets re-uploaded (i now have 4 copies of my logo ), Have only tried with logo, might be size/config changes,will check.
Also couldn’t find a category for this post which makes me really nervous I’m not seeing something obvious.
