Lightroom Classic does not release SSD Storage

Hi,

inside Lightroom Classic I've moved pictures (in the first step 160 GB, in the second step 1.5 TB) from an old SSD to a new SSD.

This moving has worked (all 96382 pictures are on the new SSD) but the storage amount of the old SSD is still the same. I would expect that I get back 160 GB respectively 1.5 TB but the old SSD has only 64 GB free.

Has anyone an idea what's wrong ? How do I get my storage space back without new formatting ?

I'm working on a MacStudio M2 Ultra with MacOS 13.4.1 and LR Classic 12.4

Both SSD's are formatted in APFS.

Greetings,

Ruediger
