Second snapshot estimated at same size as first?

Hi

Trying out kopia for backing up my external macos photos library, created an initial snapshot successfully, now added a few photos to the library in order to test updating the snapshot.
Running the same command again: kopia snapshot create same_path_as_initial_snapshot it seems like it thinks it should back up the same exact contents again, not an incremental(as expected) backup of only the added files?. It states basically the same size of what to backup as well as initial estimated time as when i did the first backup. Is this as expected and the actual backed up data from the second will be only incremental and quicker (first snapshot 1.5hrs)?

Yes, the second backup will be quick and will not store any new data.

Thx for the quick reply!, tried now and it only took 17minutes(12.8GB)
