Maybe you need to use fstrim to free up the space (if it’s not already configured by default):

Disk Trimming

Disk trimming is the procedure by which the operating system informs the underlying storage device of which storage blocks are no longer in use. It does this by issuing an ATA_TRIM command for the block. This is also known as a discard. In this way, the storage device can perform garbage collection of the unused blocks and internally prepare them for reuse. SSDs in general benefit from this, while HDDs do not. In a Linux system running on bare metal, this is relatively straight-forward. When in…

TRIM in Qubes OS
