my local files only work once.

i am on my Windows 10 PC and on the Apple Music app. i'm trying to add 2 albums to my library. i hit the three dots, select add folder to library and it works just fine. But when i go to add the second album, nothing happens. Ive tried placing the folder directly in the apple music media folder to no luck, creating a folder with both of the albums in it and selecting that as the folder that i want to upload to no luck, Has anyone else had this issue?
