I am no longer able to follow the problem(s) you are describing.
First you list Windows 8.1 as the OS and DVD-R as the media.
Then that evolves to you using DVD-RW media and apparently trying to copy files using Windows 10 DVD maker.
[Sidebar regarding Windows 10 DVD Maker: "Windows DVD Maker is a decent option for creating discs but only on Windows 7 version of the OS. The software does not work on Windows 10/8 and other OS versions and thus a Windows DVD Maker Windows 7 alternative is needed."]
What DVD software application do you have installed?
You are; however, apparently using Phillips DVD-RW 4.7 GB Optical Media provided that I correctly followed your posted response.
And another issue:
The Device Manager screenshot shows the optical drive as "Slimtype DVD A DS8A5SH USB device".
Listed/shown as a DVD/CD ROM drive.
You cannot burn DVD's/CD's to a ROM drive.
And you did not answer what OS you are trying to copy.
If you are trying to make copies of some Windows OS version that is piracy and we will not assist with piracy.
Update your post to clarify what you are doing and to correct any misunderstandings on my part.

My laptop doesn't have a DVD drive so I got an external one.
The DVD doesn't show in explorer when it's inside the drive
