Ah so the app store is to blame. Be sure to report the bug to Amazon.
I use the latest Version of ES File Explorer that I sideloaded.
It has alot more features like Move and Copy to. The one in the app store is very old.
If you have a sideloaded version of an app and it's also in the app store make sure to ignore the update notice because it won't work due to the signatures being different.
