Snapshots showing in GUI but not in share

We previously had an issue after updating the firmware to 6.9.5 that caused the share to be "unlinked" from the GUI. To resolve this, we created a new share and copied the data over.

 

Now - for some reason, the GUI is showing 848gb of snapshots but the snapshot menu shows nothing. We would like to delete all snapshots and start fresh.

 

Reading a few forum posts, i decided i should try SSH to list all vulumes. this is the result:

 

root@Reflections:~# btrfs subvolume list /data
ID 256 gen 392342 top level 5 path home
ID 257 gen 554657 top level 5 path .apps
ID 258 gen 8 top level 5 path .vault
ID 259 gen 553798 top level 5 path .timemachine
ID 264 gen 554595 top level 5 path ._share
ID 270 gen 393816 top level 5 path .purge
ID 271 gen 554640 top level 5 path Shared_Data
ID 272 gen 553523 top level 271 path Shared_Data/.snapshots
ID 281 gen 393536 top level 256 path home/admin
ID 349 gen 554247 top level 256 path home/**REDACTED**
ID 366 gen 393536 top level 256 path home/**REDACTED**
ID 2121 gen 393536 top level 256 path home/**REDACTED**
ID 2122 gen 539577 top level 256 path home/**REDACTED**
ID 4317 gen 139254 top level 256 path home/**REDACTED**
ID 19310 gen 554457 top level 272 path Shared_Data/.snapshots/12260/snapshot
ID 19311 gen 393848 top level 5 path Reflections_Share2
ID 19312 gen 393848 top level 19311 path Reflections_Share2/.snapshots

 

 

Then i tried to delete the snapshots directories to which the response was "no such file or directory".

 

I have tried a balanace and a scrub but no joy. Any advice would be greatly appreciated!
