I connect an EXT4 HDD as external USB HDD but LFSfW can only see first partition

[Olive]

Only its first partition is automatically mounted. Other partitions are not found by LFSfW. But in Windows Disk Manager, all parttions are there.
Other partitions are not swap partitions.
In fact the HDD was removed from a Synology NAS.
Why?

What I see in Disk Management:

But only first partition is shown in File Explorer:

This problem still exists - but no one cares about!??

It shows not the important files (eg. Video) - do this software not read all from a hhd used in a Synology NAS?

Diskinternals LR works like a charm - but i bought paragon linux file systems for windows and it woul be nice to get a answer and a correct working programm!
