Apple Music Subscription has destroyed my music library

I recently was subscribed to Apple Music for 3 months I guess in that process it decided to upload my entire local music library from Computer 1 and delete the local files from the computer and computer 2 made some songs stream only and deleted them. I have multiple music libraries on different computers running different versions of iTunes because on computer 1 I still prefer the older version of iTunes for my work flow and the computer can not be updated past version Mojave

Computer 1 - Mojave Mac

Computer 2 - Sonama Mac

On the Mojave Mac iTunes has uploaded 56000+ files to the cloud and now that I do not have music on my computer anymore. All of the music has the cloud icon next to it. but with out a Music subscription I can not play any of the songs.

On the Sonama Mac it deleted or removed some songs but not all, I have music in my library that is greyed out and can not locate, and then there are other songs that now says stream instead of the size of the song and when I double click on the song it just tells me I need a music subscription to play the song. I know the song was in my local library because I have date added to my music library from 2017 but I can not find the album on my computer any more.

Why would the subscription delete my local Music files and how do I get access to this music with out an apple subscription. This seems very flawed in the design of Apple Music and they should ask permission before deleting the music from my local library.
